35kV XLPE Insulated (Flame-Retardant) Power Cable

Depending on the flame retardant property, the 35kV XLPE insulated power cable is divided into two types, common type and flame-retardant type.

For the common type, it adopts advanced photo cross-linking and three layer co-extrusion technologies, so it shows the advantages of outstanding reliability, high degree of crosslinking, good resistance to high temperature, etc. Based on these features, it is suitable for power system where the conductor works at 90℃. On the other hand, the flame-retardant type uses protective jacket that is resistant to fire, and flame retardant is added to the materials which ensures the excellent fire proofing property of the cable. So, this product is applied for the places that have strict flame-retardant requirement.

Model Explanation
Model Descriptions Applications
Cu Core Al Core
YJV YJLV XLPE insulated and PVC sheathed power cable It can be laid in outdoor tunnel, cable duct, reinforced concrete pipeline and loose soil. It can not bear external mechanical force, but a certain tensile force is applicable.
YJV22 YJLV22 XLPE insulated, steel tape armored and PVC sheathed power cable It is laid underground, and it can stand external mechanical force. However, big tensile force should not be applied.
YJV32 YJLV32 XLPE insulated, thin steel wire armored and PVC sheathed power cable It is laid in tunnels, mines and indoor places, and mechanical force and quite big tensile force are both applicable.
YJV42 YJLV42 XLPE insulated, thick steel wire armored and PVC sheathed power cable It is suitable for tunnel, mine, vertical place and indoor place. In addition, big tensile force and external mechanical force won't destroy this product.

Note:
1. The models also contain flame-retardant type.
2. The single core type should not be laid in iron pipes.
3. Halogen free low-smoke power cable is also provided on customer's request.
4. 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".

Note:
1. These models contain three types, which are flame-retardant type, low-halogen low-smoke type, as well as halogen free low-smoke type.
2. Non-magnetic material or magnetic loss reducing structure should be applied to armor the single core cable.

Applications
This 35kV XLPE insulated power cable is used for transmission and distribution of high voltage power lines with rated voltage of 35kV.

Application Properties
The maximum rated temperature for the conductor is 90℃. However, its temperature should not exceed 250℃ during short circuit, and the short circuit should not last for 5 seconds or longer time. On the other hand, when laying the cable, the ambient temperature should not be lower than 0℃, otherwise, preheating is needed.

Minimum bending radius: 15 times of overall cable diameter for single core type, and 10 times of overall cable diameter for multi-core type.
