35KV MV 105 Medium Voltage EPR Power Cable

Standard of EHV Power Cable

IEC60840:1999, IEC62067:2001and IEC62067:2006

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:

Single core: ≥20(d+D)±5%.

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

Standard of EHV Power Cable

IEC60840:1999, IEC62067:2001and IEC62067:2006

Construction of EHV Power Cable

Copper (aluminum) conductor/ XLPE insulated/ corrugated aluminum sheath/ PVC (PE) sheathed

 Rated Voltage of EHV Power Cable 

 Cross Section of EHV Power Cable: mm²

 Operation Characteristics

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