In modern electrical systems, cables, as the core carriers of power transmission, their performance and quality are directly related to the safety, stability, and efficient operation of the entire system. The BV, Bvr, Thw, Thhn series of single core PVC insulated Copper Cables we launched, with their well-designed structure, high-quality material selection, and wide range of specifications, have become the ideal choice in various Electrical Wiring scenarios. From daily electricity use in family residences to power transmission in industrial plants, these cables meet the diverse power needs in different environments with excellent adaptability and reliability. Product Overview: Diversified Choices and Core Advantages
Although the BV, Bvr, Thw, Thhn series of single core PVC insulated copper cables belong to the category of single core PVC Insulated Cables, each has its unique design focus to adapt to different application scenarios. The specifications of this series of cables range from 1.5mm to 16mm, fully covering the power transmission needs from low load to high load. This diversified product layout enables users to find a matching cable model whether it is for the connection of small household electrical equipment or the power supply of large industrial machinery. Its core advantage is first reflected in the choice of Conductor Materials. The use of high-purity copper ensures excellent conductivity. As an excellent conductive metal, copper has extremely low resistivity, which can minimize energy loss during power transmission and improve power utilization efficiency. This is of great significance for reducing electricity costs and energy waste, especially in large-scale and long-term power transmission scenarios, where the advantages are more prominent. Secondly, the application of PVC Insulation layer provides comprehensive protection for the cable. PVC (polyvinyl chloride) is a polymer material with stable performance, which has good insulation, can effectively isolate current, prevent electric leakage accidents, and ensure electricity safety. At the same time, it also has excellent corrosion resistance, can resist the erosion of various chemical substances such as acids, alkalis, and salts, and prolong the service life of the cable. Moisture resistance is also a major highlight of the PVC insulation layer. Even in a humid environment, it can maintain good insulation performance and ensure the normal operation of the cable. In addition, the specially treated PVC insulation layer also has flame retardant properties. When encountering an open flame, it can delay the spread of fire and gain valuable time for safe rescue. Analysis of Characteristics of Each Model: Precise Design for Different Scenarios
BV Cable: A Stable and Reliable Choice for Fixed Wiring BV cable adopts a hard conductor structure, and its conductor is made of a single solid copper rod, which has high mechanical strength. This structural characteristic makes BV cable perform well in fixed wiring scenarios, especially suitable for trunk laying in buildings, wall concealed laying, and wiring in pipes, etc. In these scenarios, once the cable is installed, it rarely needs to be moved or bent. The hard conductor structure can ensure that the cable remains stable in shape during long-term use, and is not easy to deform or break, thus ensuring the continuity of power transmission.
For example, in the laying of electrical trunk lines in residential buildings, BV cables can be neatly arranged along the wire grooves or pipes inside the walls. With their rigid characteristics, they reduce the risk of line faults caused by external extrusion or vibration. At the same time, the hard conductor structure also makes the BV cable more firm when connected, with a large and stable contact area with the terminal, reducing contact resistance and reducing heating caused by poor contact.
BVR Cable: A Flexible and Convenient Adapter to Complex Environments Different from the hard conductor of BV cable, Bvr cable adopts a soft conductor structure formed by stranding multiple fine Copper Wires. This structure endows Bvr cable with excellent Flexibility, enabling it to easily cope with narrow spaces, complex corners, and wiring environments that need frequent bending. In home decoration, when it is necessary to lay lines in narrow areas such as behind furniture and ceiling interlayers, Bvr cables can shuttle flexibly, avoiding the installation inconvenience caused by the difficulty in bending of hard Conductor Cables. In the wiring of some electrical equipment that needs to be moved or adjusted frequently, the advantages of Bvr cables are more obvious. For example, the temporary wiring of stage lighting equipment, because the position of the equipment needs to be changed frequently according to the performance requirements, the soft characteristics of Bvr cables enable them to be bent repeatedly without being damaged, which greatly improves the flexibility and efficiency of wiring. In addition, the soft conductor structure can also reduce the internal stress generated in the cable during bending, prolonging the service life of the cable.
Thw and Thhn Cables: Strong Guardians in High-Temperature Environments
Thw and Thhn cables are specially designed for high-temperature environments. Their insulation layers are made of PVC materials with special formulas, which have excellent high-temperature resistance. Thw Cables can usually work for a long time at an ambient temperature of 90℃, while Thhn cables have more excellent high-temperature resistance, can withstand a high temperature of 105℃, and can maintain the stability of insulation performance even when encountering higher temperatures in a short time. In industrial production, many equipment will generate a lot of heat during operation, such as metallurgical furnaces, boilers, drying equipment, etc., and the ambient temperature around them is relatively high. Thw and Thhn cables can work stably in these environments, effectively avoiding electric leakage or short-circuit accidents caused by aging and cracking of the insulation layer due to high temperature. In family environments such as kitchens, wiring close to heating appliances such as ovens and microwave ovens, choosing Thw or Thhn cables can also significantly improve electricity safety.
Specifications and Applications: Precisely Matching Different Load Requirements
1.5mm and 2.5mm: Basic Guarantee for Daily Household Electricity Use
Cables of 1.5mm and 2.5mm specifications are commonly used in household electrical wiring, mainly for carrying relatively low power loads. 1.5mm cables are usually suitable for lighting circuits. The power of lighting equipment such as chandeliers, wall lamps, and spotlights in the home is relatively small, and the total current is generally not more than 10A. 1.5mm cables can fully meet their power transmission needs.
2.5mm cables are mostly used in ordinary socket circuits, which can connect small household appliances such as TV sets, refrigerators, and washing machines. The power of these appliances is usually between several hundred watts and more than one thousand watts. The current-carrying capacity of 2.5mm cables can stably support their normal operation. For example, an air conditioner with a power of 1500W, when working under 220V voltage, has a current of about 6.8A, while the safe current-carrying capacity of 2.5mm cables can reach about 25A, leaving sufficient margin to ensure electricity safety.
4mm: Reliable Support for Medium-Power Equipment
The 4mm specification cable has strong bearing capacity and is suitable for connecting household appliances with larger power, such as electric water heaters, electric ovens, induction cookers, etc. The power of these appliances is usually more than 2000W, and the working current is relatively large. The current-carrying capacity of 4mm cables can meet their needs, avoiding problems such as heating and aging of insulation layers caused by cable overload.
In small commercial places, such as convenience stores and small offices, 4mm cables are also often used for wiring of power sockets to provide stable power support for equipment such as printers and air conditioners. Its good conductivity and bearing capacity can ensure the stable power supply of these equipment during long-term work.
10mm and 16mm: Strong Power for Industrial-Grade High Loads
Cables of 10mm and 16mm specifications are large-section cables with extremely high current-carrying capacity, mainly used for high-load power transmission in industrial facilities. In factory workshops, large motors, air compressors, cranes and other equipment have huge power, often dozens of kilowatts or even hundreds of kilowatts, requiring 10mm or 16mm cables to carry their working current. For example, a 30kW three-phase asynchronous motor has a rated current of about 57A when working under 380V voltage. The safe current-carrying capacity of 10mm cables when laid in the air can reach about 65A, which can meet its needs. For equipment with higher power, such as a 55kW motor with a rated current of about 105A, 16mm cables are needed to ensure the stability and safety of power transmission. In addition, 10mm and 16mm cables are also indispensable in occasions where large current needs to be transmitted, such as the main incoming line of buildings and distribution trunks.
Materials and Technology: A Solid Guarantee of Quality
The conductor of our cable is made of electrolytic copper with a purity of more than 99.9%. High-purity copper can significantly reduce the resistivity of the conductor, improve conductivity, and reduce energy loss during power transmission. In order to ensure the quality of the conductor, the copper material will undergo strict testing before being put into production to eliminate materials with impurities, cracks and other defects.
In the conductor processing process, through advanced wire drawing technology, the copper rod is drawn into a copper wire of the required diameter (for Bvr cables, it is further stranded). During the wire drawing process, the drawing speed and die precision are strictly controlled to ensure that the diameter of the copper wire is uniform, the surface is smooth, and the decrease in conductivity caused by surface defects is avoided.
PVC Insulation Layer: A Key Barrier for All-Round Protection
The quality of the PVC insulation layer is directly related to the safety performance and service life of the cable. We select high-quality PVC resin and add auxiliary materials such as stabilizers, plasticizers, and flame retardants. After scientific proportioning and mixing, we form Insulation Materials with excellent performance. In the insulation layer extrusion process, advanced extrusion equipment is used to ensure that the insulation layer has uniform thickness, is closely combined with the conductor, and has no defects such as bubbles and pinholes. In order to enhance the flame retardant performance of the insulation layer, an appropriate amount of flame retardant is added to the material formula, so that the PVC insulation layer can be quickly carbonized when encountering an open flame, forming a flame retardant layer and inhibiting the spread of fire. At the same time, by adjusting the proportion of plasticizers, the insulation layer has both good flexibility (for Bvr cables) and sufficient mechanical strength (for BV, Thw, Thhn cables).
Strict Quality Inspection: The Last Line of Quality Control
Each batch of cables must undergo strict quality inspection after production. The testing items include conductor resistance, insulation resistance, voltage resistance performance, flame retardant performance, mechanical performance, etc. Through the conductor resistance test, ensure that the conductivity of the conductor meets the standard; the insulation resistance and voltage resistance tests verify the insulation performance of the insulation layer to prevent electric leakage accidents; the flame retardant performance test simulates the fire environment to evaluate the flame retardant effect of the cable; the mechanical performance test checks the tensile strength and elongation at break of the cable to ensure that it is not easy to be damaged during installation and use.
Only cables that pass all testing items are allowed to leave the factory to provide users with reliable products.
Applicable Scenarios and Installation Suggestions
Wide Range of Applicable Scenarios

Cables of different specifications are applied to various scenarios from household lighting and sockets to large industrial equipment according to the load size.
Installation Precautions
When installing cables, corresponding installation measures should be taken according to different cable models and application scenarios. For BV cables, due to their high hardness, attention should be paid to the bending radius not less than 6 times the outer diameter of the cable when bending, so as to avoid conductor damage or insulation layer cracking caused by excessive bending.
Although Bvr cables have good flexibility, they should also avoid excessive stretching during installation to prevent conductor breakage. When installing Thw and Thhn cables in high-temperature environments, ensure that they keep a sufficient distance from heat sources or take heat insulation measures to avoid the insulation layer being in an over-temperature state for a long time.
When connecting cables, appropriate terminals and tools should be used to ensure firm connection and good contact, so as to avoid heating caused by poor contact. At the same time, the cable should be laid away from sharp objects and corrosive substances to prevent damage to the insulation layer.
