Description

Product characteristics and application　　

Mining XLPE insulated cables are used for fixed laying under well or upper ground with A.C 50Hz and the power transmission in transmission and distribution power lines at rated voltage UO/U up to and include 8.7/10kV. The products have characters as large transmission capacity, high operating temperature, better electrical performance, better flame-retardant performance and readily to be installed etc.
The MYJV cables can be installed under well, in tubes and ducts but could not bear outside force.
The MYJV22 cables could be installed under well, in tubes, ducts and soil and could bear mechanical outside force but could not bear large pulling force.
The MYJV32 cables could be installed under well, in tubes and ducts and can bear mechanical outside force and relative pulling force as well.
The MYJV42 cables could be installed under well, in tubes and ducts and can bear mechanical outside force and larger pulling force as well.
