URD cable

1.Product Application and Features:

used for secondary distribution and underground service either direct burial or in ducts with fully insulated.

• Designed for use in electric distribution circuits not exceeding 600voltage phase to phase and may be directly buried or installed in ducts.

• Maybe used in et or dry locations at conductor temperatures not exceeding 90ºC for normal operation . 130ºC for emergency overloads and 250ºC under short circuit conditons.

2.Construction:

Concentric strand or compressed 1350-H19 conductor,polythylene or crosslinked polyethylene insulation.

3.URD cable covers mainly 3 types of the service drop cable:Duplex service drop cable.triplex service drop cable,quadruplex service drop
