Abstract
The utility model discloses an H-shaped branch joint for power cable branching, comprising a branch insulating body (1), an inserting and pulling head (2), a stress cone (4) and a pressing device. The branch insulating body (1) is formed as an entity with internal connecting hardware fittings (10, 15), a high polymer insulating barrier (11), a metal net (12), a metal case (13) and a rubber cushion (14) by high voltage injection. The inserting and pulling head (2) and the stress cone (4) are arranged in the internal connecting hardware fittings (10, 15). The utility model is an H-shaped branch joint for power cable branching of easy installation, simple structure, small volume.
Description
Technical field
The utility model relates to a kind of branch joint, particularly relates to a kind of power cable branch that can be used for underdrain or direct buried installation H type branch joint of drawing.
Background technology
Development along with China's power construction, increasing input of town and country electric power networks construction, more and more to the demand of power cable, particularly the demand of the power cable of 10kV increases especially day by day, also is to use in large quantities with respect to branch's coupling product of 10kV power cable.10kV power cable branch in the market connects the electric cable fitting product and is mainly distribution box.It is that cable is drawn out to ground, connects by each insulating sleeve unit construction, connects with the branch that reaches power cable, and need a combination cabinet be installed at the other block cable shaft that adds of cable trough, and the power cable built-up joint is placed in one; Its construction in power construction is built is loaded down with trivial details, the feeder pillar cabinet is bulky in addition, beautifying of city also brought certain influence, particularly in China big city, be difficult to satisfy it required clear position is installed, more important because casing places ground to cause artificial damage to cause unnecessary loss easily.
The utility model content
Technical problem to be solved in the utility model provides a kind of power cable branch easy for installation, simple in structure, that volume is less " H " shape branch joint of drawing.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of power cable branch " H " shape branch joint of drawing, by branch's insulating body, connect-disconnect plug, stress cone, hold down gag is formed, it is characterized in that: the skin of described branch insulating body is a metal shell, in described metal shell, be provided with polymeric dielectric layer, and between described metal shell inwall and described polymeric dielectric layer, post the layer of metal net, described branch insulating body both ends of the surface are provided with grease proofing protection against the tide and corrosion resistant rubber blanket, in described polymeric dielectric layer, be provided with in two connect gold utensil with described in be connected the tapered cable passage of the corresponding connection of gold utensil, in described, connect in the gold utensil described connect-disconnect plug is installed, in described tapered cable passage described stress cone is installed, described hold down gag is located between described stress cone end face and the described branch insulating body end face.
Described hold down gag is made up of hold-down ring, pressure strip, sealing ring, supported flange, soket head cap screw, soket head cap screw is fixed on supported flange and sealing ring on branch's insulating body, supported flange compresses pressure strip, and pressure strip is by hold-down ring compressive stres awl.
Adopt the power cable branch joint of technique scheme, branch's insulating body is that an integral body forms by interior connection gold utensil and polymeric dielectric layer, wire netting, metal shell and caulking gum by high pressure injection moulding.Particularly adopt special process to post the layer of metal net between metal shell inwall and the polymeric dielectric layer, wire netting and polymeric dielectric layer tightly are bonded as one, thus the external shield of insulating as branch well; Branch's insulating body another feature is with hold down gag stress cone firmly to be pressed in branch's insulating body, because stress cone is when inserting branch's insulating body, its gap is very small, behind hold down gag compressive stres awl, its radial dimension of stress cone compression back increases and branch's insulating body inner hole wall tightly is bonded, and has good sealing and electric property; Branch's insulating body the 3rd is characterised in that two ends have grease proofing protection against the tide and corrosion resistant rubber blanket when moulding, thereby makes the utility model can be in the abominable local safe operation of environment.
The utility model volume is little, compact conformation, and each is solid incorporate module mutually, has hard metal shell, perfect waterproof; Acid and alkali resistance, salt; Performances such as anti-mechanical stress damage, the direct ground connection of metal shell and wire netting has fault current performance preferably, simple installation, both directly direct-burried also can be installed in cable shaft or the cable trough in underground.
In sum, the utility model is a kind of power cable branch easy for installation, simple in structure, that volume is less " H " shape branch joint of drawing.
