Heat shrinkable busbar insulating tube and power supply system is widely used in urban mining, chemical, petrochemical and other industries convergence busbar substation insulation protection, no temperature issues, without reducing the busbar current carrying capacity, excellent insulation properties, good process features, easy to install, safe and reliable, comprehensive protection system is the power of choice. Rodents, snakes and other small animals caused by the fault; prevent acid, alkali, salt and other chemicals on the busbar corrosion; prevent maintenance personnel mistakenly charged the gap caused by accidental injury; adapt switchgear miniaturization trends; solve Busway The white insulation problems
