1kV/3kV XLPE Insulated (Flame-Retardant) Power Cable

1kV/3kV XLPE insulated (flame-retardant) power cable uses XLPE insulation and PVC sheath that are both flame-retardant. Compared with common PVC insulated type, it features stable performance and good flame-retardant property. Meanwhile, it is cheaper than the XLPE insulated type with same specification. Thus, it is suitable for places where good fire resistance is required but environmental requirement is not very strict.

Standards
The XLPE insulated (flame-retardant) power cable meets the GB/T 12706-2008 standard which is equal to IEC 60502-2005. Meanwhile, the flame-retardant property conforms to GB/T 18380.3-2008 which is the same as IEC 60332-2004.

Application Properties
1. Rated voltage U0/U: 0.6/1kV, 1.8/3kV
2. Long-term working temperature: 90℃
3. Short circuit: Cable temperature ≤250℃, lasting time ≤5 seconds
4. Minimum bending radius during laying: 20 times of overall cable diameter for single core type, and 15 times for multi-core type.
5. Additionally, the ambient temperature when laying cable should not be lower than 0℃, otherwise, preheating is required. The laying is not limited by the drop height.

Cable Length
Power cable is usually delivered in drum, and the total length is often longer than 100 meters. Short cable can also be delivered, but it should not be shorter than 20m, and its amount should not exceed 10% of total length. The cable can be delivered at any length, and this is negotiable. In addition, the length error is within ±0.5%.

Model Explanation

Model		Descriptions	Applications
Cu Core	Al Core
YJL YJVR(YJRV)	YJLV	XLPE insulated and PVC sheathed (flame-retardant) power cable	It can be laid indoors and outdoors, such as tunnel, cable duct, loose soil, etc. It can not bear external mechanical force, but a certain tensile force can be applied during laying. In addition, the single core type is not allowed to be installed in magnetic pipes.
YJV22	YJLV22	XLPE insulated, steel tape armored and PVC sheathed (flame-retardant) power cable	It is placed outdoors, and burying in the ground is also suitable. Meanwhile, external mechanical force is applicable, but big tensile force is forbidden.
YJV32	YJLV32	XLPE insulated, thin steel wire armored and PVC sheathed (flame-retardant) power cable	It is used in water, vertical well or places with high drop height, and it can bear external mechanical force and fairly large tensile force.
YJV42	YJLV42	XLPE insulated, thick steel wire armored and PVC sheathed (flame-retardant) power cable	It can be laid in vertical well, sea floor or places with high drop height. Pretty big positive pressure and tensile force are both applicable.

Note:
1. The models also contain flame-retardant type.
2. When signing the contract, the flame retardant type must be specified. For example, if type A is preferred, please add "A" to the end of "ZR", forming "ZRA", and A is usually used in places where the flame-retardant property is highly required. B and C follow the same rule. In addition, if there is no letter after "ZR", the cable will be produced following "ZRC".
