Main function of rubber sheathed power cord

What are the main functions of rubber sheathed power cords? Rubber sheath is the outermost layer of sheath for power lines, and its structure mainly uses copper wire as the conductor. The quantity and flexibility of copper wire are also considered factors.

1. Structure

1) Lead wire core: Made of copper flexible wire bundle twisted, with a flexible structure and a large cross-sectional surface that allows for paper wrapping to improve bending performance.

2) The insulation is made of natural styrene butadiene rubber, which has good aging performance.

3) The rubber of outdoor products is made of chloroprene rubber or a mixed rubber formula mainly composed of chloroprene rubber.

2. The universal rubber power cord has a wide range of applications, suitable for general occasions that require mobile connections for various electrical equipment, including the connection of electrical mobile equipment used in various departments of industry and agriculture.

3. According to the cross-sectional size of the rubber power cord used and its ability to withstand mechanical external forces, it is divided into three types: light, medium, and heavy. These three types of products all require softness and bendability, but lightweight rubber power cords have high requirements for softness, and should be lightweight, small in size, and unable to withstand strong mechanical external forces; Medium sized rubber power cords have a certain degree of flexibility and can withstand considerable mechanical external forces; Heavy duty rubber power cords have high mechanical strength.

4. The rubber power cord sheath should be tight, sturdy, and have a certain degree of roundness. YQW, YZW, YCW rubber power cords are suitable for outdoor use (such as searchlights, agricultural plows, etc.) and should have good resistance to sunlight aging.
