Produktbeschreibung

Introduction:

Low voltage pure-porcelain bushing with flange structure plays an important role in reducing the level of partial

discharge,improving the flexural strength and reducing leakage.

In addition ,the cast aluminum flange,instead of the previous traditional pressure claw structure,not only

improves the overall appearance of the product,but also facilitate the on-site installation.

Presently,the annual production capacity of 24kv and above voltage bushing is 30,000 and nearly 5000

supporting equipment for 110kv and above voltage current transformer is provided annually. We are capable of

high and efficient productivity in casting,processing,assembling and testing. The earliest product has been

running for more than 10years.

With continuous innovation and improvement,our products will become perfet and we will keep rolling out new

products eliminating hidden dangers in sealing bushings and achieving flexural strength and excellent

appearance.

Symbol meaning: B-for transformer; D-single insulator; F-composite porcelain insulation; J-with additional insulation; L-through cable (or current transformer can be installed), the number before „/“ in the bushing model indicates the rated voltage ( KV), the number after „/“‚ indicates the rated current (A).

The main features of transformer flange bushings are as follows: No leakage and good sealing performance. The sealing structure of the bushing is between metal flanges. After sealing, there is no gap between the upper and the lower flange, and the rubber gasket has no leakage, which avoids aging and cracking caused by the exposed rubber gasket. The rubber pads are double-line sealing rubber pads to ensure a reliable seal. It has high shock and blast resistance and good mechanical strength. The aluminum alloy flange of the bushing is produced by aviation technology, and the porcelain bushing and flange are glued together after being clamped by a special process. It has high mechanical strength, corrosion resistance and beautiful appearance, and is suitable for special environments.

No partial discharge, good electrical performance. After the optimized design, the electric field is more uniform, there is no floating potential, and the partial discharge is less than 10pc.
Reasonable structure and good safety performance. The product design has a large current carrying margin, and adopts self-cooling and oil circulation cooling design, which reduces and avoids overheating and ablation of the conductive rod during long-term or overload operation.
Easy installation and good versatility. The casing is designed according to the characteristics and conventions of the domestic industry, and can be interchanged with the existing casing. It has good versatility and is convenient for model selection and product layout. Flanged bushings reduce installation accessories and labor.
