Hebei anmei company produces various transformer accessories. The main products include high-voltage and low-voltage transfomrer bushings (DIN standard, ANSI standard, AS standard, and so on.), oil level gauge, dehydrationg breather, release valve, thermometer, valve, butterfly valve, brass gate valve, bellows, terminals,dry change accessories and so on. company can also be produced according to customer drawings. The products are exported to all world, Asia, the Middle East, South America, Europe, and so on.
Transformer bushing insulators are applied as a structure, carrying on conductor through a partition such as transformer tank and insulating it, incorporating the means of attached flange to the partition for medium voltage level.
For Entire Range of Bushings Ratings from - 1 Kv to 72 Kv & - 100 Amp. to 10,000 Amp.
All Ares Insulator transformer bushing insulators are made of ceramic materials according to IEC 672. Other Transformer bushing custom-made insulators can be supplied upon customer's request and specifications.

Product Details
It is the insulating sleeve that leads the transformer's internal high and low voltage leads to the outside of the oil tank, which not only insulates the ground as the lead, but also plays the role of fixing the lead.
Therefore, the transformer sleeve has the following requirements:
(1) it must have specified electrical strength and sufficient mechanical strength.
(2) must have good thermal stability, and can withstand the short circuit of the instant overheating.
(3) small appearance, small quality, good sealing performance, strong universality and easy maintenance folding.
The transformer sleeve is the main insulating device outside the transformer box. The lead wire of the transformer winding must pass through the insulating sleeve to insulate the lead wire between the lead wire and the lead wire between the transformer shell, and to fix the lead wire at the same time.Due to different voltage levels, the insulation sleeve has pure porcelain sleeves, oil-filled sleeves and capacitive sleeves.Pure porcelain bushing is mostly used for transformers of 10kV and below. It is to wear a conductive copper rod in the porcelain bushing, and the inside of the porcelain bushing is air insulated.The oil-filled bushing is mainly used in the 35kV class transformer. It is oil-filled in the porcelain bushing. A conductive copper pole is worn in the porcelain bushing.Capacitive bushing is composed of main insulating capacitor core, outer insulating upper and lower porcelain parts, connecting sleeve, oil pillow, spring assembly, base, equalizing ball, measuring terminal, wiring terminal, rubber washer, insulating oil, etc.It is used in high voltage transformers above 100kV.

The porcelain bushings are used extensively in electrical apparatus. Porcelain bushing is the device that enables one or several conductors to pass through a partition such as a wall or tank and insulates the conductors from it. The means of attachment to the partition, such as flange or other fixing device, forms part of the bushing.
