1. Purpose This product is used for wiring electrical appliances and instruments in power distribution devices with AC rated voltage of 450V/750V or DC voltage of 1000V and below. 2. Product use characteristics Cable The long-term allowable working temperature of conductor shall not exceed 70 ℃. The temperature of the cable during laying shall not be lower than 0 ℃. The bending radius during laying shall not be less than 10 times of the outer diameter of the cable. The cable with armored layer or copper tape shield structure shall not be less than 12 times of the outer diameter of the cable. 3. Product standard: Polychloride (GB9330.2-88) ethylene Insulation and sheath Control cable 》4. Cable model, name and scope of use: KVV PVC insulated, PVC sheathed control cables are laid indoors, in cable trenches The Conduit Inside and underground. KVVP PVC insulated, PVC sheathed copper wire braided shield control cable is laid indoors, in cable trenches, in pipelines and underground, and KVVr PVC insulated, PVC sheathed soft control cable is laid indoors and requires flexible movement. KVVRP PVC insulated PVC sheathed copper wire braided shield soft control cable has the same anti-interference ability as above. KVVP2 PVC insulated PVC sheathed copper tape wrapped shielded control cable is the same as above. KVV22 PVC insulated, PVC sheathed, steel tape armored control wires laid indoors, in cable trenches, in pipelines and underground can withstand large external mechanical forces.
KVV32 PVC insulated and fine steel wire armored PVC sheathed control cables laid indoors, in cable trenches, in pipes, shafts and underground can withstand certain tensile force.
