Poured Resin Busbar Has Better Waterproof Performance And Rated Current 400A~5000A

Sunshine Electric produces cast resin type low voltage busway trough which is a high performance low voltage busway system. The outer surface formed by the cast resin provides a watertight barrier around the current-carrying conductor. It is rated for currents up to 5000A. The insulation material is halogen-free, non-toxic and non-flammable. The phase and grounding arrangements, L1, L2, L3, are available in N, PE and N as well as PEN. neutral is 100% and PE is available is 50%. the PEN is rated at 100%. the PE/PEN line is made of the same material as the phase line. It has excellent performance and is particularly suitable for subways, shipyards, chemical industries and other applications where high demands are placed on water resistance and corrosion resistance. High safety and reliability. The busway is protected up to IP68, which meets the requirements of the protection level provided by the IEC 60529 enclosure. IP68 design allows the product to work for a period of time in water or laid in cable ducts.

Advantage

Uses a unique epoxy resin formulation that has been developed for use in waterproof busways. The resin is mixed in a sealed vacuum to ensure consistent quality, uniform distribution of the mixture, and no air voids.
Under controlled conditions of temperature and pressure, the material in the mold will gradually solidify. After curing, the resulting insulated busway is compact, void-free, with low internal stress and a smooth outer surface.
IEC 60529-compliant feeder busways are available with protection ratings up to IP68.
The degree of protection provided by the housing. IP68 design allows the product to work for a period of time in water or laid in a cable duct.
The copper conductors are processed by a polishing saw process, which ensures high quality bar ends. This process is better than cutting and avoids secondary damage to the insulation material.
