Product Description
Product Description
The feature of High voltage Combined Electric Appliance expansion joint (GIS System):
As the connector unit between the covers of two adjacent equipments, Expansion Joint for High Voltage Combined electric appliance are mainly used for adjusting the installation, compensate the relative displacement and the movement caused by expansion and contraction. Generally expansion joints always used under the condition of High Stress (Namely, large movement), but this expansion joint always used under the condition of Low Stress (Namely, small movement).
Because of the holder of the composite apparatus can't bear much pressure, so the structure should be designed to Pressure Balance Type so that the expansion joints can balance the pressure thrust produced by inside pressure rely on the elastic force of the disc spring to reduce the pressure on the holder. The composite apparatus are full of expensive media of SF6 gas, annual air leakage ≤1%,or it will lower the reliability of the products when it operating, if seriously, it will lead to the power cut and the overhaul of the whole system, so that is why require to the gas tightness is pretty high.
GIS expansion joint used as an electric elements, require the all surfaces are very smooth and no cusp, or there maybe electric discharge, influence the insulating property of the products
