Description
Technical field
The utility model relates to a kind of power cable joint, particularly relates to a kind of mesolow power cable plug-in preparation joint.
Background technology
Along with the rapid development of Chinese national economy, the power industry develop rapidly, upgrading urban and rural power grids and construction speed are accelerated, and 10kV electric cable accessories joint series products kind and demand increase rapidly.
At present, mesolow electric cable accessories joint product divides two kinds of structures both at home and abroad:
1), wrapped formula, add the containment vessel of perfusion insulation water-proof seal glue.
2), silicon rubber prefabricated (shrinkage) part structure, need adorn the containment vessel of casting insulated waterproof gasket cement when waterproof requirement is arranged.
First kind of version is used for the paper oil insulation power cable more, in today that crosslinked cable extensively uses, seldom sees on market.The joint of second kind of frame mode is to use the most at present.Their adapter body is made by silastic material; prefabricated (not predilation) and two kinds of frame modes of shrinkage (predilation) are arranged as required; itself does not have water proofing property the adapter body of this frame mode, need add the water proofing property that a containment vessel of having poured into a mould the waterproof insulation fluid sealant is realized joint.And, when such joint is installed, earlier with fitting sleeve on cable, carry out the crimping of gold utensil then, again joint is centered close to move at last and overlaps with the gold utensil center, the treated length of cable will increase like this, and the adapter body center that silicon rubber is made is difficult to really overlap with the gold utensil center, and there is hidden danger to a certain extent in this.
The utility model content
Technical problem to be solved in the utility model provides the mesolow power cable plug-in preparation joint that a kind of volume is little, in light weight, easy for installation, need not fill any insulation pouring agent, waterproof, protection against the tide, anti-mechanical damage.
In order to solve the problems of the technologies described above, the mesolow power cable plug-in preparation joint that the utility model provides, connecting cylinder is cast in the metal shell with main insulation, be respectively equipped with the wedge shape tube at described connecting cylinder two ends, be equipped with on the cable core with the stress cone of described main insulation coupling and with the corresponding occluder of described wedge shape tube, described wedge shape tube adopts plug-in to be connected with described occluder, at described stress cone and described occluder the stop cover that is complementary is installed, at described metal shell two ends end cap is installed, flange is installed in described end cap and compresses described stress cone by hold-down ring, between described end cap and the described flange sealing ring is housed, is connected with ground connection copper flexible cord between described flange and the described cable core.
Being connected to be threaded between described end cap and the described metal shell adds the binders for composite materials connected mode.
Adopt the mesolow power cable plug-in preparation joint of technique scheme, stress cone adopts polymer rubber pressure to annotate the rubber moulding, stress cone is held out against on the insulating body tapered wall by the screw thread of hold-down ring by flange and metal shell, guarantees that Product Interface is functional.Insulating body processes with advanced moulding process for High Performance Insulation silicon rubber, connecting cylinder is with integrated poured in housing by insulating material, become adapter body, abandoned adapter body and containment vessel separated structures in the past, fundamentally stopped the problem that joint makes moist, intakes and bring; The connection gold utensil is designed to plug-in and exempts from compression-molded structures, and the mounting means of gold utensil and adapter body is a plug-in, and it is extremely convenient to install; Volume is small and exquisite, installing space is little, and is in light weight; The screw thread of end cap and metal shell adds the sealing ring under adhesive connected mode and the flange, has ensured the reliable water proofing property of joint; Joint can reveal to be put or direct-burried; Maintenance free in the running.
The utility model is the mesolow power cable connector that a kind of volume is little, in light weight, easy for installation, need not fill any insulation pouring agent, waterproof, protection against the tide, anti-mechanical damage.
