What is the depth of the 10KV high-voltage pole?
There is no BVVR model in the standard specification! KVVR conductor is the fifth kind of conductor and RV, BVR than the second kind of conductor is much more soft.
According to the current standard of China's wire and cable models - . BVVR is the wire model, said the recording of ethylene insulation, recorded vinyl jacket soft core copper sheath line, is the market to see a long two or three Wrapped together in the wire, if BVV is hard core, if BLVV is aluminum core ****. . KVVR is the cable model, and is the control cable model. R represents the soft core, and no L represents the copper core.
Different standards, manufacturing standards are not the same, BVVR fixed wiring with PVC insulated PVC sheathed flexible cable, manufacturing standard reference GB / T5023.4-. generally do not use such a soft conductor structure, the voltage level of 300 / 500V, KVVR, this cable control cable, PVC insulated PVC sheathed flexible cable voltage level 450 / 750V, cable manufacturing standards for the GB / T9330-.. the voltage level is not the same, the former for AC voltage Grade 300 / 500V, the latter for AC voltage rating 450 / 750V If the specifications of the two cables are the same, KVVR can replace BVVR
