Description
Technical field
The utility model is a kind of all insulation formula busbar shiplap joint high-tension insulating bushing, to solve two outsourcing insulating layer coatings
The insulation processing of the exposed conductor of conductor overlap, belongs to high-tension distribution equipment technical field.
Background technology
At present in high voltage power distribution field, to adapt to trend toward miniaturization, conductor outsourcing insulating layer coating reduces between conductor and over the ground
Distance is the technology generally used, but two conductor overlapping part insulation measures are always a bottleneck, are typically all used
Heat-shrinkable T bush is coated or the mode of increase insulation distance solves, and assembling inconvenience is coated using heat-shrinkable T bush, also can not be in life
The standardization of part is realized in production manufacture；Heating heat-shrinkable T bush equipment is also bought, adds cost；Technics comparing is cumbersome, and zero
Part, which is broken, to be not easy to change；Insulation processing mode is realized cumbersome, is not also approved by industry；Increase insulation distance, lose again
The advantage for going product to minimize.
Utility model content
It is above-mentioned present in prior art its object is to overcome the utility model proposes a kind of high-tension insulating bushing
Defect, solve the insulation processing of two exposed conductors of outsourcing insulating layer coating conductor overlap, realize parts Standardization, convenient peace
Dress is changed, reduces cost.
Technical solution of the present utility model：All insulation formula busbar shiplap joint high-tension insulating bushing, its structure include high pressure
Insulating sleeve, there is tri- holes of A, B, C on high-tension insulating bushing, the A holes on A conductors insertion high-tension insulating bushing, the insertion of B conductors
B holes on high-tension insulating bushing, the C holes that insulated screw is inserted on high-tension insulating bushing, A conductors, B conductors pass through insulated screw
Fastening is together.
The advantages of the utility model：
1. meet the requirement of Liang Zhong conductors lap-joint all insulation；
2. the production standard of part is realized, without secondary operation during assembling；
3. reduce cost；
4. Product Assembly is convenient and simple, installed with working standard instrument；
5. it is convenient to change.
