Import Fire Retardant Busbar Trunking — Buy in wholesale FOB from Supplier in China

The fire retardant busbar trunking supplied by Shanghai Zhenda Complete Sets Of Electric Equipment Co., Ltd. is a prefabricated power distribution system that incorporates electrolytic copper conductors of 99.99 % purity and a Class‑H epoxy resin insulation layer. According to the listing, the trunking is rated for continuous currents from 250 A up to 3150 A and is classified with an IP54 protection degree, allowing resistance to limited dust ingress and water splashes. The epoxy insulation is fire‑retardant, enabling the system to operate safely at ambient temperatures up to 80 °C without loss of dielectric strength. The product is described as suitable for industrial plants, commercial buildings and critical infrastructure where reliable short‑circuit protection is required.

The trunking is typically supplied in modular sections with widths ranging from 100 mm to 300 mm and heights of 50 mm to 150 mm, allowing flexible layout in three‑phase installations. Standard length per section is 1000 mm, and sections can be joined by mechanical couplings or welding as specified by the design engineer. The copper bar conforms to IEC 60228 Class 1 standards, while the epoxy insulation meets IEC 60331 fire‑resistance criteria for Class H applications. Typical surface finish is a grey‑colored epoxy coating, and the system can be painted or powder‑coated upon request for aesthetic integration.
