Other Requirement

1. Conductor:

1.1 Compact round conductors, composed of several layers of concentric spiral-wound wires.

1.2 Segmental conductors, conductors are composed of several segment-shaped conductors assembled together to form a cylindrical core.

2. Semi-conductor screen on conductor:

To prevent electric field concentration, there is an interface of ultra-smooth semi-conductor XLPE between the conductor and the insulation.

3. XLPE Insulation:

The insulation insulates the conductor when working at high voltage from the screen working at earthing potential. The insulation must be able to withstand the electric field under rated and transient operating conditions.

4. Semi-conductor screen on insulation:

This layer has the same function as the conductor screen: Progressive transition from an insulating medium, where the electric field is non- null, to a conductive medium (here the metal cable screen) in which the electric field is null.

5. Metallic screen:

Wrinkled aluminum screen welded longitudinally

Core: single

6. Sheath:

PVC(IEC60502 ST₂) PE(IEC60502 ST₇)

7. Core identification:

Natural

8. Cable marking:

embossing or printing

9. Standard:

IEC 60840 IEC 62067 GB/T 11017 GB/T 18890

10. Application:

Used in the transmission lines between two units of an electricity distribution grid,a generator unit and a distribution unit or inside a station or sub-station.

11. Laying:

Air or directly buried

Standards

International: IEC 60840 IEC 62067

China: GB∕T 11017, GB∕T 18890

Other standards such as BS,VDE and ICEA upon request

PACKING AND SHIPPING

We are capable of meeting the strictest delivery schedules according to per purchase order. Meeting the deadline is always the top priority as any delay in the delivery of cable can contribute to overall project delay and cost overrun.

Cable is supplied in wooden reels, corrugated boxes and coils. Cable ends are sealed with BOPP self-adhesive tape and non-hygroscopic sealing caps to protect the cable ends from moisture. The required marking shall be printed with a weather-proof material on the outsides of drum according to customer's requirement.
