The cable is manufactured according to GB5023-1997 and JB8734-1998 national standard or international standard of 227IEC
Type:
227 IEC01(BV)---Copper-cored electric wire in PVC insulation
BLV---450/750V---Aluminum-cored electric wire in PVC insulation
BVR---450/750V---Copper-cored soft electric wire in PVC insulation
227 IEC10BVV---Copper-cored round electric wre with
PVC insulated & sheathed
BLVV 300/500V JBB8734.2-1998---Aluminum-cored round power cable in PVC insulation & PVC sheath
BVVB---300/500V JBB8734.2-1998---Copper-cored parallel power cable in PVC insulated & PVC sheath
BLVVB---300/500V JBB8734.2-1998---Aluminum-cored flat power cable in PVC insulation & PVC sheath
Use:
The cables can be applied to the copper(aluminum)-core
cables in the rated A/C voltageof U450/750V and below
for power, lighting, daily electric appliances, apparatus
& meter and telecommunication equipments
Using characteristics:
1.U0/U is 450/750 and 300/500 The working voltage is U450/750 and 300/500
2.Allowed long-term working temperature of cable/electric wire:Item 227 IEC 07- BV-90 not exceed 90 oC, the other items not exceed 70 oC
3.The temperature of cable laying in the air should not be less than 0 oC
4.The allowed bending radius: it should not be less than 4 times the outer diameter of the cables if the outer diameter of the cable is less than 25mm, and it should not be less than 6 times the outer diameter of the cables if the outer diameter of the cable is 25mm and above,
