Aluminium Conductor Steel Reinforced ACSR Conductor

 

Product Description

 

20kv electrical wire/20kv cable/20kv electric cable

 

APPLICATIONS

Predominantly used for primary underground distribution in conduit systems; suitable for use in wet or dry locations, direct burial, underground
duct, and where exposed to sunlight. The engineered Power polyethylene jacket allows the cable to slide through duct with less friction, resulting
in longer pulls or longer pushes with less lubricant, or in some cases, no lubricant at all. To be used at 15,000 volts or less and at conductor
temperatures not to exceed 90°C for normal operation.

 

STANDARDS

15kV Power MV Primary UD Cable meets or exceeds the following ASTM specifications:

•      B3   Soft Annealed Copper Wire

•      B8   Concentric-Lay-Stranded Copper Conductors, Hard, Medium-Hard or Soft

•      B230       Aluminum, 1350-H19 Wire for Electrical Purposes

•      B231       Aluminum 1350 Conductors, Concentric-Lay-Stranded

•      B609       Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes

 

15kV Power MV Primary UD Cable is manufactured to the latest edition of the following specifications, and in case of specification conflicts, in the
order listed:

•      ANSI/ICEA S-94-649

•      AEIC CS-8

•      RUS U-1

CONSTRUCTION

The cable is composed of a solid or moisture blocked reverse lay, compressed stranded soft drawn copper, or a solid or moisture blocked reverse
lay or unilay compressed stranded 1350-H16/26 aluminum phase conductor, covered by a semi-conducting cross-linked polyethylene strand
shield, a tree-retardant cross-linked polyethylene primary insulation, and a semi-conducting cross-linked polyethylene insulation shield.
Conductors are available with either 100% or 133% insulation levels. A concentric neutral of bare copper wires and a sunlight resistant, -40°C
rated, insulating engineered Power polyethylene jacket are applied over the insulation shield. The cable is identified by surface print on the jacket
and with the lightning bolt symbol for supply cables indented in the jacket. Red extruded stripes available upon request. A semi-conducting
engineered Power polyethylene jacket is also available upon request.

 

TECHNICAL PARAMETER LIST

Aluminum Conductor Steel reinforced (ACSR) Cables
Application
ACSR conductors are widely used for electrical power transmission over long distances, since they are ideal for long overhead lines spans. They are also used as a messenger for supporting overhead electrical cables.
Standard
Basic design to BS 215-2 / BS EN 50182 / IEC 61089 / ASTM B 232/B 232M / DIN 48204 / JIS C 3110 standards
Construction

ACSR conductors are formed by several wires of aluminium and galvanized steel, stranded in concentric layers. The wire or wires which form the core, are made of galvanized steel and the external layer or layers, are of aluminium. Galvanized steel core consist normally of 1, 7 or 19 wires. The diameters of steel and aluminium wires can be the same, or different.
By varying the relative proportions of aluminium and steel, the required characteristics for any particular application can be reached. A higher U. T. S. Can be obtained, by increasing steel content, and a higher current carrying capacity by increasing aluminium content.
