Urd Cable

 APPLICATIONS

• Predominantly used for primary underground distribution

• Suitable for use in wet or dry locations, direct burial, underground duct, and where exposed to sunlight

• To be used at 35,000 volts or less and at conductor temperatures not to exceed 90°C for normal operation

SPECIFICATIONS

35kV Primary UD Cable meets or exceeds the following ASTM specifications:

• B 230: Aluminum 1350-H19 Wire for Electrical Purposes

• B 231: Aluminum 1350 Conductors, Concentric-Lay-Stranded

• B 609: Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes

CONSTRUCTION

• The phase conductor is concentrically stranded, compressed soft copper or 1350-H16/26 aluminum alloy

• Cable is composed of the conductor with moisture block in the strands, 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

• Concentric neutral of bare copper wires and an insulating polyethylene jacket is applied over the insulation shield

• Cable identified by surface print on the jacket and with the lightning bolt symbol for supply cables indented in the jacket
