DCEH/3-100 locomotive cable, locomotive cable manufacturer
This product adopts rubber insulation and is divided into three varieties according to the different types of insulation rubber used. It is mainly suitable for the power transmission and laying connection of railway locomotive and vehicle cables with AC rated voltage of 3kV and below. It has certain characteristics such as oil resistance, cold resistance, and UV resistance.
1DCEH/3-100 locomotive cable, locomotive cable manufacturerUsage characteristics
1. Rated voltage U0/U is 500V, 750V, 1kV, 1.5kV, and 3kV. The DC rated voltage is 1.5 times the AC rated voltage.
2. The long-term allowable working temperature for cables is 70 ℃ for DCXF/2, DCH/3, and DCEH/3 products; DCH/3-100, DCEH/3-100 products have a temperature of 100 ℃.
3. The lowest operating ambient temperature for cables: DCXF/2, DCH/3, DCEH/3, DCH/3-100, DCEH/3-100 and other products should not be lower than -25 ℃.
4. Allowable bending radius for cable laying:
When the outer diameter (D) of the cable is 20mm or less, it should not be less than 3D.
When the outer diameter (D) of the cable is 20mm or more, it should not be less than 5D.
