300mm2 Cable Three Phase Cable Underground Cable

300mm2 cable three phase cable underground cable

1. Main Application
Medium Voltage cable constitutes the best cable for transmission and distribution lines because of its excellent electrical and physical properties. These cables has the advantage of simplicity in construction, lightness in weight; convenience in application besides its excellent electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with no limitation of level difference along the route.
2. Medium Voltage Cable Standards
GB/12706-2008, IEC60502-2,IEC 60228,IEC60332 ,BS 6622 , and ICEA S-66-524 ect.
*KAIQI POWER can also design and produce for special application requirement.
