XLPE insulated power cable has a number of advantages over paper insulated and PVC insulated cable.XLPE power cable has high electric strength,mechanical strength,high-ageing resisting,environmetal stress resisting antichemical corrossion,and it is simple construction,using convenient and higher operating of long term temperature.It can be laid with no drop restriction.

Various of flame-retardant and non-flame retardant XLPE cable can be manufactured with three technology(peroxide, silane and irradiation crosslinking). The flame-retardant cable covers all kinds of low-smoke low-halogen low-smoke halogen free,and non-smoke nonhalogented and three classes of A,B,C.

CU Conductor PVC Insulated PVC Sheathed Power Cable

1. The applications: Rated voltage (U0/U) 0.6/1kv 8.7/15KV 26/35kV in transmission & transformation line & for water-proofing purpose .

2. Standards: 60502IEC ISO9001

3. Product features:

1) No necessary to heat up in advance while installing above 0^oC.

2) Max. continuous normal operating Temperature: 90^oC (PVC Sheathed cable).

3) Max. Permissible temperature at short circuit (5s. at longest): 250^oC.

4) Permissible bending radius:

Three-core:≥15(d+D)±5%(D is the actual overall diameter of cable, and d is the actual overall diameter of conductor).

Detailed Description

Cross-linked polyethylene insulated power cable not only has excellent electric and mechanical properties, but also has powerful resistance against chemical corrosion, heat-aging and environmental stress. Its structure is simple and using conveniently, also can be laid with no restriction of different level. The long term operating temperature is 90, and its transmit capacitance is large.

Our company can produce both flame retardant and non-flame retardant series of XLPE power cable.. Our products can be produced according to our works specifications which are equivalent to GB12706, IEC60502, IEC60332, IEC60754, and its some indexes are superior to standards stated above..

The flame-retardant cable covers all kinds of low-smoke low-halogen, low-smoke halogen free and three classes of A, B, C. We can design and manufacture special XLPE cable according to the other standards require by the customers, such as heavy section cut part conductors, water-resistant, defend termites, defend mouse, and so on..

Operation Characteristics

During the normal operation, the max permissible continuous operating temperature of conductor should not exceed 90°C
Conductor temperature during short-circuit( 5 s maximum duration) should not exceed 250°C
The min permissible bending radius during the cable laying is normally 25 times of the cable’s OD.
The installation is not limited to the horizontal dropping varience.
Pre-heated is needed when the ambient temperature is below 0°C during installation

Application of EHV Power Cable

EHV XLPE Power cable is suitable for transmission and distribution systems in the power station.
