Zinc oxide resistor discs exhibit excellent nonlinear characteristics, with a nearly flat volt-ampere characteristic curve. They are the core component of zinc oxide surge arresters, enhancing both the operational safety of the arrester itself and the protection provided to the equipment it safeguards.
Safety tools and equipment refer to various specialized tools and instruments designed to prevent accidents such as electric shock, burns, falls, and drops, thereby ensuring the personal safety of workers.

The switchgear is designed according to the requirements of GB3906. The entire unit consists of a cabinet body and withdrawable components (draw-out units). The cabinet structure is entirely fabricated by bolting together aluminum-zinc coated steel sheets or galvanized steel sheets. The switchgear is divided into compartments for the circuit breaker, busbar, cable, and instrumentation. All metal components are reliably grounded, and each compartment in the main circuit system features an independent pressure-relief channel. Additionally, a grounding busbar measuring 10x60mm can be installed within the cable compartment.
WM Series (C-Channel) Low-Voltage Withdrawable Switchgear
The WM Series (C-Profile) Low-Voltage Withdrawable Switchgear is designed for use in three-phase AC systems with a frequency of 50 Hz, rated operating voltage of 400V (690V), and rated current up to 4000A. It serves as a versatile solution for power distribution, motor control centers, and capacitor compensation applications in power generation, supply, and industrial settings. Widely adopted in power plants, oil and gas facilities, chemical plants, metallurgical industries, textile factories, high-rise buildings, and other environments, this product complies with standards such as GB7251.1 and JB/T9661.
GGD Fixed-Type Switchgear Cabinet
The GGD fixed switchgear cabinet is designed for power users such as power plants, substations, and industrial/mining enterprises. It is suitable for AC distribution systems operating at a rated voltage of 380V and a rated current of 3150A, 50Hz, and is used for the conversion, distribution, and control of electrical energy in power, lighting, and general-purpose equipment. The product features high breaking capacity, excellent dynamic and thermal stability, and versatile performance. It complies with relevant standards including IEC 60439-1 and GB 7251.1.
A box-type substation, also known as a prefabricated substation or pre-engineered substation, is a compact, indoor or outdoor distribution device manufactured in a factory. It integrates high-voltage switchgear, distribution transformers, and low-voltage distribution systems into a single, pre-assembled unit according to a specific wiring configuration. This innovative design organically combines functions such as transformer step-down and low-voltage power distribution, all housed within a fully enclosed, steel-structure enclosure that is moisture-proof, rust-resistant, dustproof, rodent-proof, fireproof, theft-proof, heat-insulated, and highly mobile.
Box-type substations are particularly well-suited for urban grid construction and renovation projects, representing a new generation of substations that have emerged following the traditional civil-engineering-based substations. They are ideal for use in mining sites, industrial enterprises, oil and gas fields, and wind power stations, effectively replacing conventional brick-and-mortar distribution rooms and substations, thus becoming a modern, turnkey solution for comprehensive power transformation and distribution needs.
Single-phase master-controlled meter box with six-unit vertical structure
Suitable for scenarios such as residential housing for urban and rural residents and the renovation of older residential communities, this system allows for the centralized installation of six single-phase electricity meters, enabling integrated management of electricity consumption measurement, circuit control, and safety protection.
Epoxy boards are made by impregnating alkali-free glass fiber cloth—commonly used in electrical applications—with epoxy-phenolic resin, followed by baking and hot pressing. They exhibit high mechanical and dielectric properties, along with excellent heat and moisture resistance, as well as superior machinability.
Cable trays are categorized into structures such as槽式 (trough-type), 托盘式 (tray-type), 梯架式 (ladder-type), and 网格式, and they consist of components like brackets, support arms, and mounting accessories. Inside buildings, cable trays can be installed independently or attached to various structural supports found in buildings, structures, and utility tunnels. They should feature a simple design, elegant appearance, flexible configuration, and easy maintenance. All components must undergo galvanization, especially those installed outdoors in exposed environments.
Wireless High-Voltage Digital Phase Comparator
The wireless high-voltage digital phase detector is designed for phase and phase-sequence verification in power lines and substations. It features functions such as phase detection, phase-sequence measurement, and live-line testing. With its robust anti-interference capability, it meets (EMC) standard requirements and is suitable for use in environments with various electromagnetic field interferences.
