XLPE insulated electrical overhead cable

Overhead Insulated Power Cable is suitable for overhead distribution lines with rated A.C voltage U(Um) 0.6/1KV ----26(35)kV

1.Rated voltage:0.6---35kV

2.The long term working temperature of the conductor: the temperature of HDPE insulated conductor should be less then 700C. And XLPE conductor should under 900C.

3.The laying temperature should high then -200C.

4.Max .temperature of cable when short circuit (5s)

HDPE insulation 1500C XLPE insulation 2500C

5.Every fault time of single phase earthing time shall be less than one minute, shall be less than 8h per time and less than 125h each year

6.Min curving radius of cable

Single core cable: 20(D+d)u00b15%mm, TR structure is 20Dmm

Multi cores cable: 15(D+d)u00b15%mm,

Concentric strand or compressed 1350-H19 conductor, polyethylene or cross-linked polyethylene insulator composed the phase line, concentric strand AAC, AAAC, ACSR, or copper messenger line.

Primarily used for 120 volt overhead service applications such as street lighting,outdoor lighting,and temporary service for construction.To be used at voltages of 600 volts phase-to-phase or less and at conductor temperatures not to exceed 75oC for polyethylene insulated conductors or 90oC for crosslinked polyethylene(XLP)insulated conductors.
