Construction
- Range of Nominal Cross Area: 400∼2500mm2
- Compact conductor with compact index over 0.9. For conductor with cross section area no less than 1000 mm2, milliken conductor will be used.
- Inner screen consists of braided semi-conducting nylon strip (double-deck if no less than 1000mm2) and packed super-lubricity semi-conducting screen.
- Insulation made of super-purified XLPE insulation material.
- Insulation screen is made of super lubricity semi-conducting screen material.
- YJLW02 and YJLW03 have 2 layers of braided 2.0mm-thick semi-conducting waterproof strips in clearance as their cushion layer.
- YJLW02 and YJLW03 have corrugated aluminium tape as metal screen. YJV and YJY have braided copper wire no thinner than 95mm2 as metalscreen.
- Outer sheath is made of PVC or PE sheath material, a layer of 0.5∼1mm thick graphite electrode will be extruded on the surface simultaneously.
