Circuit Breakers

Circuit breakers are primarily used in power distribution systems to protect circuits, enable control operations, and manage electrical power distribution. By providing reliable overload and short-circuit protection, circuit breakers help monitor power quality, ensure electrical safety, and improve overall energy efficiency.

Our company manufactures a wide range of circuit breakers designed to meet diverse circuit requirements and application scenarios. These products are suitable for, but not limited to, industrial and commercial facilities, residential buildings, and outdoor power distribution networks.

All production processes are carried out in strict accordance with established standards to ensure that every product meets high quality requirements. In terms of materials, we carefully select scientifically validated, high-quality flame-retardant materials. In addition, all materials used in our circuit breakers are recyclable, reflecting our commitment to safety, reliability, and environmental responsibility.

Meter Box

Meter boxes are primarily designed to provide a safe, enclosed, and isolated environment for electrical devices such as energy meters and switches. They offer essential functions including dust protection, moisture resistance, anti-theft performance, and prevention of electricity tampering.

Our meter boxes are manufactured using SMC materials, which deliver high mechanical strength and strong flame-retardant properties, while also achieving a high level of protection. To meet diverse customer requirements, we offer multiple models in various sizes, allowing circuit breakers, fuses, and energy meters of different specifications to be securely and appropriately installed inside the box. This enables the formation of a modular and intelligent circuit management system.

Fuse

The primary function of fuses is to provide more precise overload and short-circuit protection. When the current rises abnormally to a dangerous level, the fuse safely interrupts the circuit by melting itself, thereby preventing damage to downstream electrical equipment and reducing the risk of electrical accidents.

Our company supplies a wide range of fuses with different breaking capacities. Dedicated fuse types are available for specific national standards, and a variety of fuse links with different ratings are offered to meet customer requirements. Featuring a simple structure and easy installation and operation, our fuses are commonly used in series with circuit breakers to provide a cost-effective supplementary solution for achieving higher ultimate breaking capacity.

Electricity Meter

Electricity meters serve as the basis for electrical energy trade settlement, providing functions such as accurate measurement and data recording, information communication and control, as well as power consumption management and analysis. They precisely measure and record the electricity usage of households or equipment, enabling remote meter reading, tariff adjustment, and power control. In addition, electricity meters help users understand their consumption patterns while supporting operators and utilities in load monitoring and energy consumption analysis.

Our smart electricity meters offer a high level of measurement accuracy and are available in both single-phase and three-phase models to suit different application scenarios. Single-phase meters are commonly used in residential homes, small shops, and most household or small commercial environments, while three-phase meters are designed for industrial and commercial applications that rely on three-phase power, such as factories, shopping malls, office buildings, and data centers. Customers can also choose from a variety of functional options, including prepaid smart meters and smart meters with remote tariff and billing control, to meet specific management and operational needs.

Power Line Accessories

Power fittings are used to provide mechanical connection and fixation within power grids, protecting key components such as conductors and insulators. Certain types of fittings also contribute to electrical connection and protection, helping to enhance operational safety and improve energy efficiency.

Our power fittings are manufactured from high-strength materials capable of withstanding significant tensile forces and complex mechanical stresses. The aluminum alloy surfaces form a dense oxide layer, which greatly enhances corrosion resistance and effectively reduces maintenance frequency. Most power fittings are designed for outdoor applications, including overhead transmission lines, substations, and converter stations, where long-term reliability under harsh environmental conditions is essential.

High Voltage Power Distribution & Protection Series

High-voltage power distribution and protection products form a critical group of equipment that ensures the safe distribution, control, and protection of electrical power from the transmission network to end users. These products enable reliable power distribution, flexible control, and rapid fault clearance under high-voltage operating conditions.

Within high-voltage distribution networks, they are responsible for the collection, allocation, and transmission of electrical energy. They can safely make and break normal operating currents and establish reliable electrical isolation points to disconnect power sources and equipment. In the event of system faults such as overloads or short circuits, these products automatically and rapidly isolate the faulty section, preventing fault escalation and safeguarding both primary equipment and the overall power grid.

Our company manufactures a wide range of products within this series. All units are produced using high-quality insulating materials and precision mechanical processing to ensure stable performance and support the efficient and reliable operation of power systems.
