Covered ACSR Conductor 150sqmm Dingo 100sqmm Dog XLPE Insulated Covered Cable

COVERED CONDUCTOR FOR MV LINES

Covered aluminum conductor steel reinforced for self-supporting system

Aluminum conductor Steel reinforced, water blocked, semi-conductor, XLPE layer, HDPE outer sheath (resistant to external conditions and to tracking).

Aluminum conductor steel reinforced The conductor shall be stranded circular (IEC 61089), based upon aluminum wires stranded around a core of steel wires. The number of wires per conductor and their diameter shall be as described on table.

1.1 Aluminum conductor steel reinforced

The conductor shall be stranded circular (EN 50182), based upon aluminum wires stranded around a core of steel wires.

The different layers conforming the conductor shall be stranded so that adjacent ones shall have opposite direction of lay and the outer layer shall be right-hand.

1.2 Semi-conductive screen

It shall consist of a fully bonded layer of black semi-conductive cross-linked compound. It shall be extruded over the conductor to provide a smooth surface without causing any damage to the conductor.

The conductor screen minimum thickness measured and accepted at any point shall not be less than 0,32 mm. In addition, the average of all the measures shall not be less than the nominal thickness (0,4 mm).

1.3 Outer sheath

1.3.1 Insulating layer

The first layer of the sheath is the insulating layer (not being the same level of insulation as a standard insulated cable). The insulation layer shall be applied by a suitable extrusion process, simultaneously with the semiconductive screen, and shall form a compact and homogenous body. In addition, it shall be possible to remove it without creating any damage to the conductor.

This layer shall be built in XLPE compliant with IEC 60502-2 characteristics, with nominal thickness as described in table follows. The minimum thickness measured and accepted at any point of the insulation layer shall not be less than 90% of the nominal value minus 0,1 mm.

1.3.2 Protective layer

The second layer will be an extruded covering layer and will provide resistance to adverse weather conditions, electrical tracking, ultraviolet radiation and mechanical abrasion. It shall be adhered to the insulating layer. Besides the characteristics indicated herein, the material shall be compliant with Polyethylene designation ST7 as described in standard IEC 60502-2.

The minimum thickness measured and accepted at any point of the protective layer shall not be less than 90% of the nominal value minus 0,1 mm.

Aluminium conductor steel reinforced – ACSR – BS

AL1/ST1 (British Standard)

EN 50182

old: BS 215-Part 2

Description

The conductors are stranded,circular compressed aluminum. The conductor screen is the extruded Semi-conducting conductor shield in Black. The inner Insulation is mainly natural color thermoplastic polyethylene (PE) or cross-linked polyethylene (XLPE). And the outer Insulation is mainly thermoplastic polyethylene (PE) or cross-linked polyethylene (XLPE) in Black or Grey with Weather or UV resistant. This standard covers both thermoplastic and cross linked polyethylene constructions, rated for 75°C or 90°C normal service temperature.
