Yje wire and cable

Yje is a kind of power cable. The full name of Yje cable is: copper-core cross-linked polyethylene insulated low-smoke halogen-free polyolefin sheathed flame-retardant and fire-resistant power cable.

Yje wire and cable characteristics

Rated voltage of cross-linked polyethylene insulation: 0.6/1, 1.8/3, 3.6/6, 6/6, 6/10, 8.7/10, 8.7/15, 12/20, 21/35, 26/35. The maximum working temperature of the conductor is 90 ℃, the short-circuit temperature (lasting for the longest 5s) is ≤ 250 ℃, the ambient temperature during laying is ≥ 0 ℃ (preheating is required when the temperature is lower than 0 ℃), and the allowable bending radius during laying is: the single-core cable is not less than 15 times the outer diameter of the cable, and the multi-core cable is not less than 10 times the outer diameter of the cable.

Difference between wire and cable yje and yjv

1. Meaning of cable code YJ: cross-linked polyethylene insulation E: polyolefin sheath V: PVC sheath.    2. The structural jacket material is different. The jacket material of yjv is PVC. The jacket material of yje is polyolefin.    3. Scope of use yjv: laid indoors, in tunnels, cable trenches and pipelines, or buried in loose soil. The cable can withstand certain laying traction. Yje: Basement and subway have fire protection places, and the fire retardant type is general.
