MYJV42 Coal Mine Used XLPE Insulated Coarse Steel Wire Armored PVC Sheathed Power Cable

Application

Technical Data

TECHNICAL DATA:

Rated voltage:(U₀/U)0.6/1 kV;(U₀/U)8.7/10kV

Temperature classification:The cable conductor is permitted to have a maximum long-term operating temperature not exceeding 90℃.During a short circuit(with the maximum duration not exceeding 5 seconds),the maximum temperature of the cable conductor does not exceed 250℃.When laying the cables on the ground,the ambient temperature during the laying process should not be lower than 0℃.

Min.Bending Radius:3 core:12(D+d)±5%

Finished product voltage test:Wire core:3.5kV/5minutes

Installation scenario:It can be used in indoor environments,tunnels,cable trenches,or underground direct burial,in damp environments and areas with high groundwater levels.It can withstand certain mechanical external forces and certain tensile forces.Indoor,tunnels,cable trenches,shafts or underground direct burial,etc.,can withstand mechanical external forces and certain tensile forces.
