INQUIRY

Product Overview

This page summarizes Xingda's full range of epoxy resin bushings — three series, 27 specifications. The red epoxy-cast insulation is a dry, oil-free design; compared with porcelain, it is lighter and more explosion-proof, ideal for dry-type transformers, pad-mounted substations, switchgear and the LV compartments of European-style compact substations.

The three series: ① BFG series (1.2kV, 1000~6500A) LV high-current bushings — 18 specifications, terminal pads 80×80 to 125×125, cover openings Φ57~Φ150, each current step available with -90° / -0° terminal direction; ② 24~36kV series (250~630A) MV bushings — 4 specifications; ③ BFGW series (35kV, 315A) outdoor epoxy bushings — 5 configurations (external-thread stud W / internal-thread N; gland-plate flange P / cast-resin flange S), creepage 1256~1650 mm.

Designation: BFG-voltage/current-terminal angle (e.g. BFG-1/2000-90°); MV models are written as voltage/current (e.g. 36/630); outdoor types add W (BFGW-35KV/315A). Internal codes follow XD.GSTG.xx.A/B.

Why Xingda

Epoxy resin bushings are fully manufactured by Tianjin Xingda. Tooling for all three series and 27 specifications is in place and supply is stable; listed dimensions refer to standard products, and non-standard heights, special hole patterns and other terminal angles can be customized to customer drawings. The dry-type epoxy line is produced in the same factory as the five porcelain lines (GB, ANSI, NBR, DIN, EN), covering both oil-immersed and dry-type transformers from a single purchase. Every bushing is delivered with sealing and mounting flanges, ready to assemble on the tank cover.
