Anqiang Power is a leading manufacturer of high voltage circuit breakers. Our high voltage circuit breakers are mainly divided into two categories: indoor and outdoor. Outdoor high-voltage circuit breakers have rated voltage levels of 24KV, 27.5KV, 33KV, 40.5KV, 66KV, 126KV, and 220KV, and are generally used on power grid lines, in large power plants, etc. Indoor high-voltage circuit breakers have rated voltage levels of 12KV, 17.5KV, 24KV, and 36KV, and are generally used in high-voltage switchgear. Anqiang's high-voltage circuit breakers have been exported to many countries in Southeast Asia, the Middle East, and Africa, and we can customize products according to user needs and drawings.

Product Introduction

High voltage circuit breakers are core switching devices in power systems, mainly used in power systems with rated voltages of 3KV-1100KV and above. Their main function is to ensure the control of circuit switching and fault protection.  These products are widely used in power generation, transmission, distribution, and industrial fields.

Working Principle

The core working principle of a high voltage circuit breaker is arc extinction. The overall working process of the product is divided into three stages: closing, normal opening, and fault opening. Therefore, a high-voltage circuit breaker is mainly composed of four components: the contact system, the arc extinguishing system, the operating mechanism, and the insulation system.

Maintenance Precautions

1. Regularly check all components of the circuit breaker for any abnormalities;

2. Regularly check the vacuum level of high voltage circuit breakers, and regularly test the gas leakage rate of SF6 circuit breakers;

3. Regularly check the lubricating oil of the operating mechanism to ensure smooth operation;

4. Regularly clean the insulation components of the high-voltage circuit breaker, and replace them promptly if they show signs of aging;

5. Regularly verify all functions of the high-voltage circuit breaker to ensure they meet technical requirements.

Anqiang Power is a China factory specializing in load switches.  Our products have voltage ratings of 12KV, 24KV, and 40.5KV.  These high-voltage electrical devices bridge the gap between circuit breakers and disconnect switches, capable of interrupting rated load current and certain overload currents, but not short-circuit currents. Anqiang can also provide product selection recommendations and customization based on customer application scenarios.

Product Categories

Anqiang's load switches are available in indoor and outdoor versions, and the products are widely used in various applications such as power distribution rooms in industrial and mining enterprises, power distribution rooms in high-rise buildings, power distribution boxes in residential areas, and new energy photovoltaic power stations. Available models include outdoor SF6 load break switches, indoor SF6 load break switches, FZN type load break switches, and FZW type load break switches.

Product Selection Guide

There are many models and specifications of disconnect switches. Anqiang Power will guide you on how to choose the right disconnect switch based on the following points:

1. Determine the rated voltage, rated current, and other product parameters of the disconnect switch you need to purchase;

2. Determine whether the disconnect switch will be installed indoors or outdoors, and obtain detailed information such as the environmental pollution level, altitude, ambient temperature, and seismic intensity;

3. Understand what functions the disconnect switch needs to fulfill, whether it only needs isolation functionality or also requires grounding functionality;

4. Clearly understand the operating method of the disconnect switch: manual, electric, or remote control.

Services and Commitments

1. Anqiang Power recommends suitable disconnect switch models to customers based on circuit requirements, environmental conditions, and safety level requirements;

2. We conduct a full range of type tests from raw materials to finished products to ensure the reliable quality of every product before it leaves the factory;

3. After cooperation, Anqiang will provide installation guidance, commissioning services, and subsequent safety operation training;

4. Anqiang will also provide readily available spare parts to support the safe and stable operation of the power grid.

Anqiang Power is a China factory that manufactures instrument transformers. These transformers are used in relay protection devices for measurement purposes. Our high-voltage instrument transformers are classified by function into current transformers and voltage transformers; and by product composition into dry-type transformers and oil-immersed transformers. They are used throughout the power system, including power plants, transmission and distribution substations, high-voltage distribution networks, new energy power stations, industrial and mining enterprises, and large commercial centers.
