Enforcement standards
YD/T1173
Purpose
This cable is used in power transmission and distribution lines in mobile situations with a rated voltage of 0.6/1kV and below.
Usage Features
The long-term working temperature of the cable does not exceed 70°C. When short-circuited (the maximum time does not exceed 5s), the maximum temperature of the cable core does not exceed 160°C, the laying environment temperature is not lower than 0°C, and its minimum bending radius is not less than 6 times the outer diameter of the cable. times.

Product Features
This product has flame retardant properties and uses a sheath material with high flame retardant properties, which greatly improves the flame retardant and fire-resistant properties of the cable. This product is suitable for places with high flame retardant requirements, such as high-rise buildings, subways, power stations, large industrial and mining enterprises and other places with high cable laying density and strict fire protection requirements. Compared with ordinary flame-retardant cables, this cable also has soft characteristics and a small bending radius, making it suitable for occasions with high bending and mobility requirements.
