All national and international standards of IEC, AS / ZNS, BS, ICEA, TCVN or some other standard.
- IEC 62067 (ABOVE 150KV)
The conductive core material is usually copper or aluminum braided round or Segments compressed in accordance with international standard IEC 60228 or according to customer's
Insulation:Insulation is made of ultra-clean cross-linked Polyethylene:
The core, insulation and insulation screens are extruded simultaneously in one process to ensure that gaps from all positions between layers are prevented
Extrusion processes are performed under the control of air pressure and an X-ray system.
In some special cases Tree-XLPE insulation will be used upon request from the customer.
Copper tape (or copper wire or lead sheath if specified) will be applied to the outside of the insulating screen.
Liner / separator
Polyethylene (PE) or PVC plastic
In the event that no armor is specified, the outer sheath will be applied directly to the outside of the screen.
The sheath that protects cables from mechanical agents is formed by the armor of steel strands, or steel tapes.
If the cable is single-core and is designed based on the choice of line, then the armor will be made with non-magnetic material (fiber or aluminum tape).
The outer shell
This sheath is made up of PVC or PE material.
These cables are manufactured with special properties under fire conditions such as flame retardant cables, low smoke cables or smoke-free cables and cables emitting toxic gases.
In other cases it will be manufactured to satisfy the requirements against termite attack.
