MV Bus Bar Tubing

A bus bar in electrical power distribution refers to thick strips of copper or aluminum bars that conduct electricity which are normally configured in metal enclosed and metal clad medium voltage switch gear. IEP DSG-Canusa CBTM/CBTH is specifically designed to insulate straight or bent bus bar which permits clearance reduction in many applications. The tubing sleeve conforms tightly to bus bars and shrinks to the required insulation thickness to provide adequate electrical protection for the voltage rating of the equipment. Coupled with CMVBT Series of medium voltage tape insulation products, IEP DSG-Canusa CBTM/CBTH provides a comprehensive range of insulation solutions for electrical equipment and retrofit applications.
