Product Description

Company introduction

    We are a professional manufacturer integrating production and trade, specializing in transformer bushings and accessories. With 30 year experience in R&D and manufacturing of transformer bushings, we own an independent production base and a complete production supply chain.
    Our production base covers an area of 8,000 sq.m, equipped with more than 50 sets of special purpose production equipment. We adopt zoned production and refined inventory management. Customized stock preparation is available to guarantee prompt delivery. Benefiting from the proximity to Tianjin Port, we achieve high efficiency export logistics with competitive transportation costs.

  Main Products 
    We supply a full range of transformer bushings complying with international standards including IEC, ANSI, DIN, EN, Australian Standard and Brazilian Standard. Our bushings cover voltage levels from 10 kV to 45 kV and rated current from 50 A to 6000 A, with custom high voltage bushing solutions available. Featuring reliable dielectric strength and mechanical performance, our products strictly follow standards such as EN 50180, DIN 4253, IEC 60137 and IEEE C57.19.100. We also deliver one stop supporting transformer accessories, including valves, breathers, temperature controllers, radiators, transformer oil and various insulating materials. 

Core Advantages 
We implement strict raw material quality control, applying high purity copper, high strength epoxy resin, anti age porcelain and weather resistant sealing components. A full range inspection system covers incoming material check, in process monitoring and pre delivery test. Our lab is fitted with professional testing instruments: X ray spectrometers, ultrasonic flaw detectors, power frequency withstand voltage testers, salt spray testers and more.

  We have obtained ISO 9001, ISO 14001 and ISO 45001 certifications, together with BV and TUV test reports as well as embassy authentication. Multiple patents and software copyrights back our solid technical capability and consistent product quality.

The transformer bushing is the outlet device that leads the high and low voltage leads inside the transformer to the outside of the oil tank, with specified electrical strength and sufficient mechanical strength. The coil connected with the bushing ,its voltage level determines the insulation structure of the bushing. The using current of the bushing determines the cross section of the conductive part and the structure of the Wiring head.

Service conditions and performance of ordinary bushing
1. Ambient temperature: Minus 45 centigrade to 45 centigrade.
2. Altitude: ordinary bushing shall not exceed 1000m, and reinforced and Anti-fouling bushing shall not exceed 2500m.
3. Ordinary bushing is suitable for light pollution areas, and anti pollution bushing is suitable for heavy pollution areas.
4. Installation angle: the vertical or inclined angle shall not exceed 30 degrees.

Delivery & Services 
    Standard products are kept in stock and can be delivered within 5~10 working days. The lead time for non standard customized bushings is 15~20 working days. Sample orders are supported, and full process inspection service is accessible.

Market Presence 
    We maintain cooperative relationships with over 100 transformer manufacturers domestically. Our products are exported across the Middle East, Southeast Asia, South America, North America, Africa and other regions worldwide, delivering stable and holistic solutions for transformer accessories.
