Product Introduction
Product Description
This Porous Resin Dry‑Type Transformer Bushing (2.5kV/5500A) is developed for high‑current low‑voltage working conditions. The Porous Resin Dry‑Type Transformer Bushing (2.5kV/5500A) is integrally cast with modified epoxy resin. Its porous structure optimizes heat dissipation and can steadily carry rated high current up to 5500A. The Porous Resin Dry‑Type Transformer Bushing (2.5kV/5500A) adopts all‑dry design instead of traditional oil‑insulation, avoiding oil‑leakage risk. Integrated assembly of conductor, resin insulation body and mounting flange brings strong compatibility for various transformer mounting dimensions. Every unit passes strict electrical, sealing and porosity tests before delivery, delivering stable performance for bulk export supporting.
Performance Parameter
Creepage distance:≥70mm
Technical Specification
Low‑Voltage Porous Resin Dry‑Type Bushing for Transformer (2.5kV 5500A) is developed for high‑current oil‑immersed transformers. Adopting porous resin casting technology, it delivers outstanding insulation performance, with 15kV power‑frequency withstand voltage and 45kV lightning impulse level. Featuring 3150N high cantilever tolerance, it resists mechanical vibration for stable operation. The ≥70 mm creepage distance adapts to harsh working conditions. Both parallel and perpendicular mounting types are available with 6‑20 holes and complete L & LA dimensions for easy selection & installation.
