One embodiment of the present invention are: described insulating coating can be made by the silicon rubber pressure injection, and its inwall has all insulation, full-shield structure.
One embodiment of the present invention are: the quantity of described draw-in groove can equal the quantity sum of all contacts.
One embodiment of the present invention are: described contact can adopt high conductivity, highdensity red copper to cold pressing and form, and its surface is coated with one deck silver.
The invention has the beneficial effects as follows:
The present invention encloses above contact contact ring by the different contact of two groups or more length is set thereby make two link all be formed with two circles or two.Therefore, the beneficial effect that has following difference prior art:
1, increase the effective area that electrically contacts between the excellent type contact of contact and ring main unit, dispersion contact heating point has improved local temperature rise, provides high electric conductivity.
2, identical contact is divided into the long and short two group, and the resistance when the excellent type contact that has reduced ring main unit advances the contact contact ring that inserts bus tie makes the splicing between the cabinet more laborsaving.
3, can increase the excellent type contact diameter of ring main unit, change Φ 13 into by general Φ 12, thereby effectively lower the ampacity of excellent type contact unit are, lower the temperature rise of conductor, thereby reach the purpose that prolongs product useful life and cut down the consumption of energy, simultaneously bus tie of the present invention also can with the product of normal dia usefulness mutually, be the energy-conserving product of a new generation, will produce the huge social benefit.
4, bus tie of the present invention is widely used in the medium-voltage distribution equipment, as the connection of SF6 ring main unit row and the socket connection of other hermetically sealed all insulations.
