Description
Technical field
More specifically refer to mesohigh power transmission and distribution and the special rigidity of high ferro transmission of electricity the present invention relates to a kind of equipment for power transmission and distribution
Terminal.
Background technology
At present, in power system, the hv cable termination being connected with trolley line, mainly stress cone type or stress tubular type
, its product has two kinds, and one kind is to use silicon rubber, integrates the integral prefabricated electricity of stress cone or stress tube, full skirt and insulation
Cable terminal, shortcoming is without rigidity.Another product is filling insulating oil or the Silica hydrogel in insulating sleeve, shortcoming for heavier,
There are oil leak hidden danger or gel to include by defects such as bubble impurity.The stress cone type hv cable termination being connected with trolley line it is intrinsic
Shortcoming be：Non-uniform electric, weatherability are poor, be easily deformed, affected by environment serious in implementation process.
The content of the invention
Uniform it is an object of the invention to provide a kind of Electric Field Distribution, ageing resistance, weatherability are good, deform small high-tension electricity
Power cable.
To achieve the above object, the present invention provides a kind of mesohigh rigidity terminal, including high-tension cable, and ecto-entad is successively
It is protective coverings of cable, metal screen layer, semi-conductive layer, high-voltage insulation layer, interior semi-conductive layer, cable metal core；By high-tension electricity
The end section of cable removes protective coverings of cable, metal screen layer, semi-conductive layer, high-voltage insulation layer, interior semi-conductive layer successively, exposes
One section of cable metal core, it is characterised in that the cable metal core is crimped together with binding post, with pre-formed one
The High-Voltage Insulation main body and stress cone of body are enclosed within cable high-voltage insulation layer, then are inserted in pre-formed rigid casing, afterbody gold
Category support sealing.
Further, the high-voltage insulation layer is silicon rubber and epoxy tube.
Further, the mesohigh rigidity exterior of terminal is provided with full skirt.
The rigid terminal has global formation dry type structure, is not just leaked without oil-filled, and rigidity is whole under environment temperature
Without liquid dilation phenomenon in end.Without there is no heat shrinkable pipe material using stress tubular goods, had using global formation
Electric Field Distribution is uniform, and ageing resistance, weatherability are good, the advantages of deform small.Cable is connected with outside line to form reliable branch
Support, and with overlength creep distance.
