Description：
One, the cable's brief introduction:
Plastic insulated control cableApplicable to industrial and mining enterprises, energy transport sector, for ac rated voltage up to 450/750 v control, approaches and protecting circuits using PVC insulated, PVC sheathed control cable.
Execution standard: GB9330.1-88
GB9330.2—88
Three, types and names:
KVV - copper core PVC insulated, PVC sheathed control cable.
KVVPL - copper core PVC insulated, PVC sheathed aluminum foil shielding control cable.
KVV 22 - copper core PVC insulated, PVC sheathed steel tape armoured control cable.
KVVRP - copper core PVC insulated, PVC sheathed braided shielding control cable.
KVVP 2 - copper core PVC insulated, PVC sheathed copper tape screened control cable.
KVVP - copper core PVC insulated, PVC textile shielding control cable.
KVVR - copper core PVC insulated, PVC sheathed control cable.
Fourth, using features:
Rated voltage U0 / U for 450/750 v.
Conductor wire core long-term working temperature is 70 ℃, 105 ℃, the cable laying temperature is not lower than 0 ℃.
Recommend the bending radius should not less than 6 times of cable diameter.
Structure of armoured or copper tape screened cable, should not be less than 12 times of cable diameter.
Five, the size reference data:

Six, said method, for example:
Plastic insulated and sheathed control cable conductor by the model, some conclusions and the nominal cross section.
Different conductors of same breed with specified structure, soft conductor (B), said after the specifications.For example, are as follows:
1, PVC insulated and sheathed control cable, 16 core, conductor nominal cross section was 2.5, 105 ℃, expressed as a hard conductor structure: KVV - 105-16 * 2.5 soft conductor structure: KVV - 105-16 * 2.5 (B)
2, cross-linked polyethylene insulated PVC sheathed double steel belt type sheathed flame-retardant control cable, 12 core, conductor nominal section 4 was, expressed as: KYJV22 12 x 4
Seven, length of delivery:
No armoured cable delivery length of 500 m, armored cable is 200 m;The number of short delivery of the goods, and allowed more than 30 m no more than 10% of the total delivery;If you have special demand, supply and demand both sides can be negotiated separately.
