Description

The following cross linked insulation aluminium alloy of high density polyethylene (HDPE) sheath 35kV electric power cable

Technical field

The utility model relates to a kind of power cable, relates in particular to the following cross linked insulation aluminium alloy of a kind of high density polyethylene (HDPE) sheath 35kV electric power cable.

Background technology

Present raising along with all trades and professions automaticity, both at home and abroad to " electromagnetic compatibility " this in the past ignored problems obtain confirming, and the in addition standard of being formulated standard, originally can not satisfy present requirement as the used plain edition cable of transferring electric power, particularly in the frequency conversion loop because unavoidably exist high order harmonic component to disturb, the contiguous distribution line electrical system of interference effect by transmission channel (cable), brought hidden danger for the normal operation of whole system, and high-temperature behavior is poor, poor insulativity, useful life is short, can not satisfy people's demand.

The utility model content

The purpose of this utility model provides the following cross linked insulation aluminium alloy of a kind of high density polyethylene (HDPE) sheath 35kV electric power cable, to overcome at present existing power cable above shortcomings.

The purpose of this utility model is to be achieved through the following technical solutions:

The following cross linked insulation aluminium alloy of a kind of high density polyethylene (HDPE) sheath 35kV electric power cable, comprise some cores, core comprises conductor wire core and ground connection core, and described conductance core and ground connection core include conductor and insulating barrier, and insulating barrier is coated on the conductor outside, described core is coated with belting layer, gap between belting layer and the core is provided with filler, and belting layer is provided with screen outward, and screen is provided with sheath outward, sheath is provided with armour outward, and armour is provided with oversheath outward.

Further, described conductor is aluminum alloy materials.

Further, described insulating barrier is polyethylene, polyvinyl chloride or butadiene-styrene rubber material.

Preferably, described oversheath is high-density polyethylene material.

The beneficial effects of the utility model are: the utility model is applicable on the following electric power output distribution circuit of 35kV makes transmission of electric energy, this cable not only has the ability of excellent electric property, mechanical performance, heat aging property, environmental stress resistance and resistance to chemical corrosion, and characteristics such as simple in structure, in light weight, long-term work temperature height, practical, safe and reliable.
