This article focuses on the manufacturers of steel wire armoured (Swa) cables of models such as 3X35mm² Yjv32, Yjy32, Wdzn - Yjy32, and Zr - Yjv32. Yjv32 represents a copper - core cross - linked polyethylene insulated fine steel wire armoured polyvinyl chloride sheathed power cable. Yjy32 is a copper - core cross - linked polyethylene insulated fine steel wire armoured polyethylene sheathed power cable. Wdzn - Yjy32 is a copper - core cross - linked polyethylene insulated fine steel wire armoured polyethylene sheathed low - smoke, halogen - free, flame - retardant and fire - resistant power cable. Zr - Yjv32 is a copper - core cross - linked polyethylene insulated fine steel wire armoured polyvinyl chloride sheathed power cable with flame - retardant properties.​ These cables are suitable for AC 50HZ power transmission and distribution lines with a rated voltage of 35KV and below, and are used for transmitting electric energy. The allowable long - term operating temperature of the conductor is 90℃, and the temperature does not exceed 250℃ during short - circuit (with a maximum duration of not more than 5s). The ambient temperature during laying should not be lower than 0℃. Due to the fine steel wire armoured structure, they can withstand mechanical external forces and considerable tensile forces, and are suitable for high - drop areas. At the same time, some models such as Wdzn - Yjy32 have low - smoke, halogen - free, flame - retardant and fire - resistant properties, and Zr - Yjv32 has flame - retardant properties, which can meet the safety requirements of different scenarios.​ Manufacturers usually produce according to relevant standards such as GB/T12706. The products are widely used in urban power grids, mines, factories, fire - fighting systems, emergency power supply lines and other places, ensuring the stable transmission of electric power in various complex environments. When choosing cables, users need to rationally select appropriate models according to the specific laying environment, load, and requirements for cable characteristics (such as flame - retardant grade, whether low - smoke and halogen - free are required, etc.) to ensure the safe and reliable operation of the power system.

YJV32 3×150mm²+240mm² steel wire armoured cable is a power transmission line suitable for harsh environments, featuring high strength, resistance to mechanical damage, and excellent insulation performance. Its structure consists of multiple parts: the conductor is made of high-purity copper to ensure conduction efficiency; the insulation layer is cross-linked polyethylene (XLPE), which has a wide temperature resistance range (usually -40℃ to 90℃) and excellent electrical insulation performance, effectively preventing the risk of electric leakage. The cable core configuration includes 3 main cores of 150mm² and 1 neutral core of 240mm², meeting the requirements of three-phase four-wire power systems. It is suitable for medium and high-voltage power transmission scenarios, such as industrial plants, underground laying, and outdoor direct burial. The outer armour is made of galvanized steel wire, forming a solid protective layer that can resist external extrusion, impact, and gnawing by rodents, significantly improving the cable's durability in complex environments. In addition, the cable has chemical corrosion resistance and waterproof performance, adapting to humid, dusty, or slightly corrosive environments. It offers flexible installation methods, supporting direct burial, pipe threading, or overhead laying, and is widely used in power engineering, mining, construction, and other fields to provide stable power guarantee for key facilities.

This cable is a 3-core Steel Wire Armoured (SWA) cable with a specification of 3X240mm². The conductor is available in copper or aluminum, offering high conductivity and lightweight advantages respectively. The copper conductor has a copper content of over 99.9%, with excellent conductivity, suitable for high-power transmission scenarios; the aluminum conductor weighs only 1/3 of the same specification copper conductor, with lower installation costs, suitable for medium and low-load circuits.​ The insulation layer adopts a composite structure of cross-linked polyethylene (XLPE) and polyvinyl chloride (PVC): XLPE has a temperature resistance range of -40℃ to 90℃ and an insulation resistance of ≥1000MΩ, which can resist high-voltage impact and temperature fluctuations; the outer PVC sheath has a tensile strength of ≥12MPa, wear-resistant and corrosion-resistant, and can adapt to complex environments such as humidity and dust. The steel wire armouring layer is made of high-carbon steel with an armouring density of ≥90%, which has excellent mechanical protection capabilities, can withstand external extrusion and stretching, and is suitable for harsh laying methods such as direct burial and pipe 穿.​ The cable has a rated current-carrying capacity of 420A (copper conductor)/320A (aluminum conductor) and a rated voltage of 10kV. It is widely used in industrial plant power distribution, main lines of high-rise buildings, outdoor overhead and underground transmission projects, providing stable and reliable guarantee for high-power equipment and long-distance power transmission.
