Circuit Breaker and Switchgear Accessories

Electrical Contacts
Our company is a major manufacturer and supplier of power equipment in China. To ensure the quality of products, our company has adopted advanced production technologies and hired professional engineers and technicians.
Electrical Conductor
Made of T2 red copper, our copper conductive parts include circuit breaker contact arms, PT contact arms, and stationery contacts, which are the most important parts of high and medium voltage
High Voltage Insulating Components
Our insulating parts include various contact boxes, insolated bushings (also known as wall bushings), insulators (also known as supporting insulators), sensors and insulating cylinders.
Racking Mechanism
Founded in 1996, we are a China based circuit breaker manufacturer and supplier. Through constant efforts of our dedicated staff, we can offer customers a great variety of circuit breaker accessories, like racking mechanism.
Interlock Mechanism
Founded in 1996, we are a China based power equipment manufacturer and supplier. Through constant efforts of our dedicated staff, we can offer customers a great variety of VCBs, switchgears, interlock mechanisms, contacts, and others. In addition, our location in Shanghai gives us easy access to convenient air, land and sea transportation.
Electric Indicating Devices
As a China power equipment manufacturer and a power transmission expert with over 18 years of experience, we at TELLHOW can offer customers a wide range of switchgears and switchgear accessories, including electric indicating devices, moving contacts, conductive parts, etc.
Embedded Poles
The embedded pole has a high dielectric strength and strong weather resistance. It also features circuit miniaturization and being solid, reliable and maintenance-free. Now the embedded pole set the trends for development of medium voltage circuit breaker
Heat Shrink Tubing
In addition, we can manufacture tailored heat shrink tube according to customers’ specific requirements. We are committed to offering high quality products and thoughtful customer services.
SMC/GPO3 Electrical Insulating Sheet
Our insulation material features high arc resistance, high dielectric strength, high pressure resistance, low water absorption rate, low strain rate, small warpage and more.
High Voltage Fuse
This electrical protective component is used in the transformer and other electrical equipment to prevent overload, short circuit or other electrical problems.
Switchgear Lamp
The housing and cover of CM series switchgear lamp are made from high strength and high-temperature resistant materials. The switchgear lamp features good transparency, small size, good safety performance, and easy replacement. It is an ideal light fixture for switch cabinet in various models.
Connector Assembly
GDZ-58 secondary plug and socket is used for secondary line connection of GZS1 (with VS1, VD4) and other mid-set high voltage switchgear. This CD series connector assembly for secondary line connection can be used in circuit breakers of various brands.
Other Accessories
We are a professional power equipment supplier based in China. In addition to supplying switchgears, we also provide a series of electrical accessories, such as cable clamps, terminal blocks, plug sockets, etc. They brings good using experience and show excellence in details.
