Power Transformer Capsule

he rubber diaphragm and capsule for the large power transformer is a protective device to prevent degradation of the transformer oil and ageing of insulation materials to prolong service life of the transformer. It can be used in a fully sealed oil reservoir tank on the 110 kv, 220 kv and 500kv transformers.

Low weight, excellent sealing performance, hot oil resistance and weather resistance, excellent ageing performance, long service life (over 10 years) and without pollution to the oil.

Working temperature: -30 C～95 C

Working medium: #25 transformer, oil, air

Specification: Manufactured as per user’s requirements.

Rubber capsule (diaphragm) of transformer storage tank Introduction

Transformer Conservator (Air bag) Transformer Conservator based on Nylon Rubber ,vulcanized at high temperature in a vacuum offers to the electrical transformer market. The raw material made of a high resistance polyamide thread, external coating designed to provide very high resistance to transformer oil, internal protection resistant to nitrogen and atmosphere agents including ozone. The weight of the nylon rubber is no more than 1.54kg/m2. The coating can resist -40Degree Celsius in 2hours without cracks and break. No crack and obvious changes at 100Degree Celsius, in 70hours.No air leak in 30 minutes after the air is flated under 20KPO.

The function of the conservator is to line inside of the conservator tank in transformers, allowing for changes in oil volume, while protecting the oil from any type of contamination or external corrosive agents, such as air, ozone, nitrogen, humidity, etc. The size can be made according to customers’ requirements. It offers a large range of specifications and shapes and sizes to fit every need. Advantages: Elimination of the air/oil contact and of condensation. Vulcanized-in flange which precludes the possibility of leakage. Elimination of oxidation and hydrolysis that might stem from air contact. Interior fabric reinforcement at points of contact with level indicator to preclude the possibility of puncture. Excellent impermeability to oil/gases and water vapour, through the use of a vulcanised-in barrier material. Quick-response Manufacturing to meet customer designs. Large range of flanges to meet any requirements. Easy and quick assembly, Super service life in contact with air and oil. High mechanical resistan.

This product provides enough elastic space to adapt to special applications and wide shapes and sizes to meet all kinds of needs. It can be applied to cylindrical, elliptical and rectangular transformer oil conservator.

he function of the soft capsule is to be installed in the transformer storage tank to accommodate the change of oil volume, while protecting the oil from any type of pollution or external corrosion such as air, ozone, nitrogen and moisture.

The soft capsules are made up of high elastic coating fabrics, vulcanized in a high temperature vacuum environment, the fabric reinforced structure is made up of high performance polyamide wire, and the outer coating has high resistance to transformer oil design, internal resistance to nitrogen and atmospheric corrosion agents, including ozone.

his product provides enough elastic space to adapt to special applications and wide shapes and sizes to meet all kinds of needs. It can be applied to cylindrical, elliptical and rectangular transformer oil conservator.

Soft capsules have many advanced features:

– avoid contact and condensation of air and oil

– the possibility of avoiding the leakage of the vulcanized flange interface

Avoid oxidation and hydrolysis caused by air contact.

There is an internal reinforcement structure at the junction between the capsule and the liquid level indicator to prevent rupture.

– because of the use of sulfurized and moisture proof materials, it has excellent oil, gas and steam permeability.

It can respond to customer’s needs quickly and produce according to the requirements of customers.

– multiple flange size, suitable for any demand

Fast simple assembly

It has super long service life under contact with air and oil.

High mechanical resistance

 Rubber capsule (diaphragm) of transformer storage tank Storage and transportation:

The capsules should be stored in a warehouse with a temperature of 0 to 28°C and a relative humidity of at least 80%, at least 1 m away from the heat source, and avoid contact with substances harmful to rubber such as acids and alkalis and prevent sharp objects.

Capsules should be handled with care in order to avoid heavy pressure and prevent mechanical damage.
