Abstract
The utility model provides a four-core crosslinked cable thermal contraction type terminal, this terminal is equipped with four sinle silks, and the cladding has the insulating tube on the sinle silk, and the one end of every sinle silk is equipped with the terminal, and the other end passes four-core branch cover respectively and is wrapped up in together by the inner cushion layer, and the inner cushion layer is equipped with the copper ligature outward, and the copper ligature is equipped with the steel armour outward, and the steel armour is equipped with cable sheathing outward. And a wire core insulating layer is arranged between the wire core and the insulating tube. The utility model discloses when having simplified original heat shrinkage type terminal structure, improved its security when in actual application on the electric power circuit.
Description
One, technical field
The utility model belongs to electrical equipment technical field, particularly a kind of four-core crosslinked cable thermal shrinkage type terminals.
Two, background technology
Prior art: prior art: in recent years, along with rapid economic development, urbanization process is accelerated, the startup of the carrying out in a deep going way of the upgrading of rural power grids, urban network restructuring, and the use of power cable in electric power system is more and more widely.In the eighties in 20th century, the power cable manufacturing technology obtains upgrading, and crosslinked polyethylene (XLPE) insulation has progressively replaced original paper oil insulation and obtained develop rapidly, at present the domestic XLPE insulated power cable that can produce the 500kV electric pressure.And as the essential electric cable accessories of cable system operation also along with more new development and develop rapidly continues to bring out various novel accessory product in recent years of cable technology.The thermal shrinkage type terminal is still occupied leading position in 10～35kV crosslinked cable annex.But present thermal shrinkage type terminal causes safety in utilization low because there is incomplete place in structure.
Three, summary of the invention
Technical problem: the utility model provides a kind of four-core crosslinked cable thermal shrinkage type terminals at above-mentioned technological deficiency, and these terminals are simple in structure, the fail safe when having improved practical application.
Technical scheme: technical solution of the present utility model is: a kind of four-core crosslinked cable thermal shrinkage type terminals, these terminals are provided with four cores, be coated with insulated tube on the core, one end of every core is provided with terminal, the other end passes the four-core spider respectively and is bundled together by inner cushion layer, inner cushion layer is provided with the copper binding wire outward, and the copper binding wire is provided with the steel armour outward, and the steel armour is provided with cable cover(ing) outward.
Be provided with the core insulating barrier between described core and the insulated tube.
Beneficial effect: when the utility model has been simplified original thermal shrinkage type terminals structure, improved its fail safe during practical application on power circuit.
