We mainly produce 6kV-72.5kV high and low voltage complete sets of equipment and high-voltage electrical equipment. Our core products include: indoor and outdoor vacuum circuit breakers, high-voltage disconnect switches, grounding switches, load switches, generator outlet disconnect switches, fuses, surge arresters, insulators, and power fittings, etc. We can provide complete sets of

Question 2

Does the company possess formal production qualifications and certifications?

Accepted Answer

The company is a formal high-tech enterprise, certified by the ISO9001 quality management system. All high-voltage products have passed national authoritative testing and type testing. We possess legal qualifications for production, sales, bidding, and supply, and can provide a complete set of qualification documents, test reports, and certificates of conformity.

Question 3

Do your products support customization, OEM, and project-specific support?

Accepted Answer

Yes. Customized production is available based on project conditions, drawing parameters, and power grid standards. We support engineering support, OEM manufacturing, and bulk supply, meeting the needs of various projects, including State Grid, rural power grids, industrial enterprises, and photovoltaic/wind power.

Question 4

What is the difference between indoor and outdoor circuit breakers?

Accepted Answer

Indoor circuit breakers (VS1/VD4 series) use epoxy resin insulation and steel plate cabinets, featuring a compact structure suitable for indoor switchgear use and offering high cost-effectiveness. Outdoor circuit breakers (ZW series) use silicone rubber composite insulation and stainless steel enclosures, providing waterproof, sunproof, anti-flashover, and salt spray resistance, allowing for all-weather use on outdoor poles.

Question 5

What is the service life and maintenance-free period of a vacuum circuit breaker?

Accepted Answer

Conventional vacuum circuit breakers have a mechanical life of over 10,000 cycles. The arc-extinguishing chamber maintains a stable vacuum, enabling long-term maintenance-free operation under normal conditions. Only annual routine inspections, bolt tightening, and insulation cleaning are required.

Question 6

Can circuit breakers be used for frequent opening and closing?

Accepted Answer

Yes. Vacuum circuit breakers have excellent arc-extinguishing performance and no risk of combustion or explosion, making them ideal for frequent switching of transformers, capacitors, and motor loads. They are currently the mainstream switching equipment in power distribution systems.

Question 7

What is the difference between a disconnect switch and a circuit breaker?

Accepted Answer

Circuit breakers are used for load switching and fault short-circuit protection; disconnect switches do not have arc-extinguishing functions and are mainly used for voltage isolation, creating a clear break, and ensuring maintenance safety. The two must be used together.

Question 8

What are the special advantages of generator outlet disconnect switches?

Accepted Answer

Specifically designed for generator outlet operating conditions, they feature high current, vibration resistance, high insulation, and strong dynamic and thermal stability. They are suitable for frequent operating conditions in power plants and generator sets, ensuring stable operation and high safety.

Question 9

How long is the product warranty period?

Accepted Answer

All high-voltage electrical equipment of the company is guaranteed for 1-3 years (adjustable depending on the product type). During the warranty period, free repair and replacement of parts are provided for non-human-caused damage. Lifetime technical consultation and maintenance services are provided.

Question 10

How long after ordering will the goods be shipped?

Accepted Answer

Standard models are readily available and can be shipped within 2-3 days; customized non-standard products will be produced within 3-7 days, depending on the production schedule, with nationwide fast logistics delivery.

Question 11

Do you support on-site technical guidance and installation/commissioning?

Accepted Answer

Yes. We provide a full range of technical services for engineering projects, including technical coordination, drawing confirmation, on-site installation guidance, commissioning Q&A, and acceptance cooperation.

Question 12

Can you provide bidding documents, authorizations, and qualification lists?

Accepted Answer

Yes. We can provide a full set of bidding documents free of charge, including manufacturer authorization, three certificates, test reports, type test reports, company profile, and bidding materials, to assist clients in bidding for projects.

Question 13

In which scenarios are the products mainly used?

Accepted Answer

Widely used in all high and low voltage power distribution projects, including State Grid, rural grid renovation, industrial parks, factory power distribution, real estate power distribution rooms, photovoltaic and wind power stations, mines, water conservancy, schools and hospitals, and old power grid renovation.
