SWA Armoured LSOH Power Cable Low Smoke Zero Halogen Cable 185mm2

Insulation Screen

The insulation screen consists of an extruded layer of non metallic, semi-conducting compound extruded over the insulation of each core. The extruded semi-conducting layer shall consist of bonded or cold strippable semi-conducting compound capable of removal for jointing or terminating. As an option, a semi-conducting tape may be applied over the individual cores or core assembly as a bedding for the metallic layer. The minimum thickness is 0.3 mm and the maximum resistivity is 500 Ohm-m at 90°C. The screen is tightly fitted to the insulation to exclude all air voids and can be easily hand stripped on site. The insulation screen is not necessary for both PVC and EPR/HEPR insulated 1.8/3.6KV and 3.6/6KV Electrical Cable. The screen may be covered by semi-conductive water blocking swellable tape to ensure longitudinal watertightness.

Inner Covering & Fillers

For Electrical Cable with a collective metallic layer or Electrical Cable with a metallic layer over each individual cores with additional collective metallic layers, semi-conducting

inner covering and fillers shall be applied over the laid up cores. The inner covering and fillers are made of non hygroscopic material like polypropylene, except if the cable is to be made longitudinally watertight. The inner covering is extruded in general but may be lapped if the interstices between the cores are filled.

The approximate thickness of extruded inner coverings is given in Table 2:

Metallic Layer 

The metallic layer may be applied over the individual cores or the core assembly collectively. The following types of metallic layers are provided:

1) Metallic Screen

2) Concentric Conductor

3) Metallic Sheath

4) Metallic Armour

The metallic screen shall consist of either copper tapes or a concentric layer of copper wires or a combination of tapes and wires. The concentric conductor is applied directly over the inner covering. The metallic sheath consists of lead or lead alloy applied as a tightly fitting seamless tube. The metallic armor consists of either flat wire armor, round wire armor, and double tape armor.

Separation Sheath (for armored cable):

The separation sheath comprises a layer of extruded PVC, PE or LSZH applied over the laid up cores under the armor. PVC is normally of grade ST2 and PE of grade ST7. The nominal thickness is calculated by 0.02Du + 0.6mm

where Du is the fictitious diameter under the sheath in mm. For Electrical Cable without a lead sheath, the nominal separation sheath thickness shall not be less than 1.2mm. For Electrical Cable where the separation sheath is applied over the lead sheath, the nominal separation sheath thickness shall not be less than 1.0mm.

Lapped Bedding (for armored lead sheathed cable):

The lapped bedding applied to the lead sheath consists of either impregnated/synthetic compounded paper tapes or a combination of two layers of these paper tapes followed bya few layers of compounded fabulous materials. The thickness is around 1.5mm.

Armour (for armored cable):

The armor is applied over the inner covering helically. It consists of either flat galvanized steel wire armor (strip), round galvanized steel wire armor, and double steel tape armor.

Over Sheath
Overall sheath comprises a layer of extruded either thermoplastic compound (PVC ST3 type or PE ST7 type or LSZH) or elastomeric compound (polychlorprene CSP or
chlorosulfonated PE). The nominal over sheath thickness is calculated by 0.035D+1 where D is the fictitiuous diameter immediately under the over sheath in mm. For unarmored Electrical Cable and Electrical Cable with the over sheath not applied over the armor, metallic screen or concentric conductor, the nominal over sheath thickness shall not be less than 1.4mm. And for Electrical Cable with over sheath applied over the armor, metallic screen or concentric conductor, the nominal over sheath thickness shall not be less than 1.8mm.
