The diameter and length of the cast busbar can be customized according to actual needs, with excellent mechanical and electrical properties. The cast busbar duct is made of high-performance insulation Resin The bus duct is cast by pouring a variety of inorganic minerals, and the busbar is directly cast and sealed, with a protection level of IP68 A new type of metal-free housing with four protection functions: waterproof, fireproof, anti-corrosion and explosion-proof Bus duct Cast bus duct can be applied to various harsh and high-clean environments, and is widely used in shipbuilding, papermaking, power plants, substations, petrochemicals, steel metallurgy, mechanical electronics and large buildings. The connection method of cast bus is more solid and reliable than the traditional bolt connection, and has good heat resistance, corrosion resistance and fatigue resistance. It will not have problems such as loosening and corrosion, thereby improving the safety of power equipment. Since the electrodes and connection methods of cast busbars are made of large diameter and high conductivity materials, the conductivity of power equipment can be greatly improved, current loss can be reduced, and power efficiency can be improved.
