Electric substation's low-pressure side uses 10kV, 35kV voltage class, and with the increasing of main transformer capacity, step down side enters the volume of line side
Determine electric current also continuing to increase.Insulating tube type busbar is because its current-carrying capacity is big, high mechanical strength, appearance and size are small, electric insulation
The strong advantage of performance, the environmental suitability that it is installed is preferable.Within the time of last decade, insulating tube type busbar is in transformer station, hair
Power plant and large-sized photovoltaic generation engineering etc. have obtained increasing application in field.
Current middle voltage insulation tube type bus includes metallic conductor, partly leads screen layer, and insulating barrier partly leads screen layer, metal
Ground shield and restrictive coating, using cross-linking radiation individual layer heat-shrink tube as partly leading screen layer and insulating barrier, but existing hold art
Screen layer is led with cross-linking radiation heat-shrink tube first time set one and half to be heated in conductor tube, then cover a layer insulating heat shrink,
Insulating barrier heat shrink is covered again, the need for repeatedly cumulative insulating barrier is to reach voltage class, then covers one layer of screen layer heat shrink,
Screen layer is so partly led with insulation interlayer because potential difference is big, easily there is air or impurity between each layer, cause High-Voltage Insulation
Tube type bus cause shelf depreciation to puncture or explode in operation.And individual layer set method, irradiation in process of production and
Heating expansion process efficiency is lower, and energy consumption is higher, and product quality is more unstable.The too thick irradiation of insulating barrier individual layer at present cannot be continuous
Production, the electron accelerator 5.0MEV of current largest domestic, Continuous maching thickness is most thick also just to reach 7.0mm, and single insulation
Layer production is too thick, and being inserted in rear operation cannot complete with current technology in heating process.
