11kv Middle Voltage Aluminum Overhead Power Cables Triplex Service Drop Wire

11kv middle voltage Aluminum Overhead Power Cables , Triplex service drop ABC cable

1 Definition:

It is a new overhead power cable. Widely used in overhead transmission line. It is mainly used for lighting, outdoor lighting, and temporary service. Phase voltage for 600 v or less, and the conductor temperature does not exceed 75 degree polyethylene insulated conductors and cross-linked polyethylene insulated 90 degree conductor (PE).

2 Feature:

1.  Good insulation properties.

2.  good corrosion resistance.
3.  against external damage and reduce the impact by trees, flying airborne objects, metal film and dust external factors, reducing phase short circuit and ground fault.

3 Operating Characteristics

Rated Voltage: Up to and including 0.6/1(1.2)kV

Max. Operating Temperature of Conductor: 90oC(XLPE), 70oC(PE), 70oC(PVC)

Max. Short-circuit Temperature of Conductor: 250oC(XLPE), 130oC(PE), 160oC(PVC)

Min. Ambient Temperature under Installation: -20oC

4 Construction

ABC aerial Cable are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. They can improves safety and reliance of electrified wire netting.

Phase conductors are concentrically stranded EC Grade aluminum wires, insulated with either black weather resistant cross linked polyethylene (XLPE) or polyethylene (PE). The conductor insulation is marked with longitudinal ridges for phase identification.

Neutral messengers are concentrically stranded AAC or 6201 Alloy or ACSR. Neutral messenger can either be bare or insulated, depending on ABC aerial cable design.

a Phase Conductor construction:
The phase conductor is aluminum alloy 1350-H19 hard-drawn, compressed concentric-lay-stranded.
b Neutral Conductor Construction
Cable assemblies are available with the following neutral conductors:
Aluminum conductors, coated-steel reinforced (ACSR), concentric-lay-stranded
Aluminum alloy 1350-H19 hard-drawn, concentric-lay-stranded
Aluminum alloy 6201-T81, concentric-lay-stranded
c Insulation Material
The standard insulation on the phase conductor is black low-density crosslinked polyethylene (XLPE)
Alternatively, black linear low-density polyethylene (LLDPE) insulation with a 75°C temperature rating is available upon request.
