Difference between YJV cable and VV cable

Jun 20,2018

YJV, VV are two types of cables with different insulation materials. General indoor permanent projects tend to choose YJV cables. VV cables are generally used for low-voltage systems and YJV cables are used for high-voltage systems. YJV cable is superior to VV cable in temperature resistance, pressure resistance and corrosion resistance. Only the price is more expensive.

Difference between YJV cable and VV cable

YJV-copper cross-linked polyethylene insulated PVC sheathed power cable.

VV - copper core PVC insulated PVC sheathed power cable.

YJV—voltage level (kV) 6～500, maximum allowable operating temperature 90°C.

VV-voltage level (kV) 1 ~ 6, the maximum allowable operating temperature 65 ~ 70 °C.

The VV cable is a PVC insulated PVC sheath that is a thermoplastic material.

YJV cable is a cross-linked PVC insulated PVC sheath, which is a thermosetting material.

Because of the different materials, VV and YJV cables allow different maximum temperatures for long-term operation.

1. The maximum rated temperature of VV cable conductors is 70 degrees Celsius, and the shortest temperature (less than 5 seconds) does not exceed 160 degrees Celsius.

2. YJV cable (YJLV) cable conductors operate at a maximum rated temperature of 90 degrees Celsius. When short-circuited (less than 5 seconds in duration), the maximum temperature does not exceed 250 degrees Celsius.

Therefore, the two types of cables have different current carrying capacities and YJV is larger.

Cable BV, BLV, VV, VLV, KVV several meanings?

Wire and cable in the power system, especially in the transmission line is essential, it also has several categories, there are special cables, insulated cables, the following will be the most comprehensive introduction!

Difference between YJV cable and VV cable

Wire and cable products:

1. What does BV, BLV, BVVB, BVR, RV, RVS, RVV, QVR, AVVR, VV, VLV, and KVV in wire and cable mean?

These symbols are some models of wire, B series belong to the cloth wire, so the beginning with B, voltage: 300/500V wire is divided into electromagnetic wire and universal insulated wire according to purpose. Insulated wires are also called fabric wires.

Insulated wire (wire) refers to a wire that covers an insulating layer, and includes various connecting wires and mounting wires.

V is PVC PVC, which is (plastic)

L is the code of aluminum core

T is the copper core code (generally omitted or not)

R is (soft) meaning, to be soft is to increase the number of conductors

BV copper core PVC insulated wire

BLV aluminum core PVC insulated wire

BVR copper core PVC insulated soft wire

Above wire structure: conductor + insulation

Take 2.5mm2 as an example:

BV is a diameter of 1.78mm and 7 0.68 two kinds

BLV is a diameter of 1.78mm

BVR is 19 diameter 0.41mm

RV copper core PVC insulated connecting flexible wire
