Dense busbar groove, the maximum protection level can reach IP66, short-term withstand current up to 120KA. Products according to the latest IEC60439-1/6 standard about splicing two-body intensive design, with fast heat dissipation, good dynamic thermal stability, low impedance, low loss and other characteristics, through 9 degrees seismic test, service life of more than 30 years. The product from design to planning, installation to operation, efficient and reliable, convenient and flexible, forward-looking new busway.

Epoxy cast type refractory busbar groove is a fully enclosed busbar, whose structure is to place a three-phase rounded rectangular copper bar vertically in the mold, and then vacuum cast it into a whole in the mold with insulating materials. Like other types of closed busbars, it can be prefabricated into standard straight sections, 90-degree bending sections, T-joints, thermal expansion compensation elements, disk joints (specially used for switch cabinets, transformer connection parts), etc.
The insulating material outside the conductor of the full cast bus is quartz sand and a suitable amount of resin mixture, adding flame retardant, with fire, water, dirt resistance, good insulation performance, good heat dissipation, less space, easy installation, maintenance-free and so on.
