Product description

Product Introduction

This 1.3kV 160‑800A Brazil NBR Porcelain Transformer Bushing is a standardized special accessory adapted to Brazilian power working conditions. Designed for local outdoor environments with high temperature, high humidity and strong sunlight, it adopts structures and materials compliant with local assembly standards. Equipped with T2 pure red copper conductor to reduce operating temperature rise, high-glaze porcelain body features pollution and aging resistance, while high-acrylonitrile NBR seals withstand long-term transformer oil immersion. With high interchangeability, it is applicable for new transformer assembly and old equipment replacement. Multiple current ratings fit oil-immersed distribution transformers of various capacities, supporting bulk supply for local power projects.

Core Advantage

Standard Compliance: Compliant with ABNT NBR 6140 standard, perfectly compatible with local oil-immersed transformers with great interchangeability.
