FZW32-40.5/T1250-25 outdoor high voltage isolate vacuum switch is a new generation of high voltage electrical equipment developed by both home and overseas advanced technology. Each of the technical performance have reach the standard of GB3804 and IEC.
They are designed for the construction and reform of urban and rural grid. The bottom of the product has adopted stainless steel and galvanized carbon steel with ultraviolet-proof coating material, to make sure it’s normal outdoor operation. Each stainless steel component can ensure it’s durability, stability, water-proof and salt fog against ability.
It has characteristic of small size, light weight, good appearance, easy operation, strong breaking ability, long electrical life maintenance free and obvious fracture. It can adopt manual single-pole operation and also electric, distance operation.

Wuhan Feite Electric Co., Ltd. is a hi-tech enterprise specialized in producing vacuum interrupters. Our company has a group of experts and technicians who have been specialized in producing vacuum interrupters for more than thirty years, and enjoys the tax preferential policy as a hi-tech enterprise.
Products and technology of our company
Our company has developed 1.14kv-40.5kv vacuum switch tubes of more than 100 types, which can be widely used for various vacuum circuit breakers, contactors and load break switches. As an ISO9001:2000 certified company, our production process strictly conforms to quality management system.
The optimum design of 40.5kv vacuum switch tubes has been developed by our company together with prestigious institute, making diameters and measurements greatly matching electric field. The leakage rate has been controlled in less than one-thousandth by Once Seal-Exhaust Technique, making technical data (such as contact bouncing duration) can be easily adjusted during mounting process, and mechanical life of our products can be largely enhanced. We have already applied for the national patents, including 2009200832892, 2009200834277, 200920083534X, 2009200835320, 2009200835335, and 2009200832905.
Component and material supply
Materialized static iso-pressure ceramic pipes: The density is much higher than injection moulding, so the welding ability is great. Many of our components are imported and environmental friendly.
Our company has 128 staff members at present, including 28 senior and medium class technicians, 2 Americans born in China and 2 experts at provincial and ministry level.
Our company persistently sticks to the synchronization of management innovation and technical innovation. We are not only constantly expanding sales network, but also introducing modern management pattern, ceaselessly promoting management, and optimizing and perfecting management structure. We will keep quality commitment to customers, and ceaselessly offer perfect service to all customers. Feite believes that we will have a bright future.
