A overhead insulated cable for tropical island area

The utility model provides an overhead insulated cable for tropical island area, includes conductor, crosslinked polyethylene insulating layer, its characterized in that: the cladding has the high density polyethylene sheath outside the crosslinked polyethylene insulating layer to at the annular slot that the surface surround cable sets of high density polyethylene sheath multichannel was parallel to each other, the section of annular slot is the V -arrangement. The utility model discloses set up and to prevent that the insulating layer from by salt air corrosion, can solve the cable heat dissipation and setting up the contradiction between the sheath through the annular slot on the sheath behind the sheath to the wind pressure that the cable received can be reduced by annular slot, the swing of cable is slowed down.
