YJV is a cross-linked polyethylene insulated power cable, referred to as (XLPE) is a plastic cable, the texture is relatively hard, the temperature rating is 90 degrees, and the voltage level is also higher from 1KV-220KV; it is suitable for fixed laying, and there are high-voltage cross-linked cables and low-voltage cables. Cross-linked cables.

YC is a general-purpose heavy-duty rubber cable, referred to as rubber cable, with a soft texture, a temperature resistance of 70 degrees, and a voltage of 450/750V, suitable for mobile laying.

1. Different product structures

YJV cables are mainly composed of conductors, polyethylene insulators, fillers (nylon), PVC composite materials, etc. ), PVC sheath, in which the conductor is mostly copper core, and the filler is mostly nylon and other materials to protect the core; if it is an armored power cable, a layer of steel strip will be added between the filler and the sheath Armoring to prevent the stress of cables buried in the ground. The steel tape armored model is YJVPVC sheathed in 22 very common. PVC material.

YC cables mainly use copper wire conductors and rubber insulation, the insulation layer is made of pure natural rubber, and the conductor oxygen-free copper has good conductivity.

2. Different implementation standards

YJV cable executive standard: GB/T12706-2008.
YC cable executive standard: JB8735-1998.

3. Working temperature is different

The ambient temperature of YJV cables is 25 degrees and the working temperature is 80 degrees.
The ambient temperature of the YC cable is 25 degrees, and the working temperature is 65 degrees.

4. Summarize other differences

1. The materials used are different: the insulation and sheath materials of YC rubber cables are all rubber. Vinyl chloride (PVC)
2. The voltage level is different: the rated voltage of YC type cable is 450/750V and below, while the rated voltage of YJV type cable is 0.6/1KV and below.
3. Different use occasions: YC cables are used in various electrical equipment such as mobile power cords for household appliances, electric machinery, electrical equipment and appliances. YJC is used as fixed laying power transmission and distribution energy.
4. The maximum long-term service temperature of the conductor is different: the maximum allowable operating temperature of the YC cable conductor is 65°C, while the maximum allowable temperature of the WDZN-YJV cable conductor is 90°C.
