Product Center
Low voltage switchgear GGD
The GGD series low voltage switchgear is an assembled advanced type of power distribution and asynchronous motor control equipment for the AC 380V system. It is suitable for power plants, petroleum, chemical and other industries for power transmission, distribution and power conversion.
AC armored withdrawable metal enclosed switchgear KYN28A-12/24(Z)
The KYN28A-12(Z) indoor AC armored removable central metal enclosed switchgear is a complete set of power distribution equipment for the 3.6 - 12KV three-phase AC 50HZ single bus and single bus sectionalized system.
240 kW Integrated DC Charging Pile with Dual Connectors
The 240 kW Integrated DC Charging Pile with Dual Connectors is a high-power fast charging solution designed for public EV charging stations, highway service areas, commercial fleets, and urban charging infrastructure. The integrated design combines power modules, control systems, and charging connectors in a single cabinet, enabling efficient power distribution and simultaneous charging for two electric vehicles.
Prefabricated Cabin-type Modular Substation
The Prefabricated Cabin-type Modular Substation is a compact and integrated power distribution solution designed for rapid deployment in power systems, renewable energy plants, industrial facilities, and infrastructure projects. All primary and secondary equipment—including medium voltage switchgear, transformers, low voltage distribution panels, and protection systems—are pre-installed and factory-tested within a prefabricated cabin, significantly reducing on-site installation time.
10 kV Compact Double-layer Prefabricated Substation
The 10 kV Compact Double-layer Prefabricated Substation is an advanced space-saving power distribution solution designed for urban infrastructure, commercial complexes, industrial parks, and renewable energy applications. The double-layer structure optimizes equipment layout by separating medium voltage, transformer, and low voltage systems vertically, significantly reducing installation footprint while maintaining high operational reliability.
Residential PV and Energy Storage Integrated Unit (HLK-EQ-5)
The Residential PV and Energy Storage Integrated Unit (HLK-EQ-5 5 kW / 15 kWh) is an all-in-one energy solution designed for residential solar power systems. It integrates photovoltaic power generation, energy storage, inverter functionality, and intelligent energy management into a compact system. The unit enables households to maximize solar energy utilization, reduce grid dependency, and ensure reliable backup power during grid outages.
Intelligent universal circuit breaker HLKEW1
The HLKE-W1 intelligent universal circuit breaker suits 50Hz AC power distribution networks up to 690V, with rated currents 400A-6300A. It distributes power and protects lines/equipment from overload, undervoltage, short circuit, single-phase grounding, and leakage.
Medium-voltage vacuum circuit breaker VQ1(ZN63A)
Designed for controlling and protecting key equipment like transformers and busbars, it swiftly interrupts circuits during short circuits or overloads to safeguard substation operations. It also executes switching operations per power system requirements for optimal power distribution and dispatch.

About Us
In the early 21st century, in order to fill the gap in the electrical switch manufacturing industry in Hunan Province, the Wangcheng Economic Development Zone at the national level in Changsha vigorously introduced the electrical switch industry of Elite. With the support and coordination of relevant leaders at the provincial, municipal and district levels, and with the strategic layout of Elite Group in the inland market of China, the R & D and manufacturing base of Elite with an investment of 200 million RMB was established in the Wangcheng Economic Development Zone in Hunan.
As a new layout of the company with its headquarters in China, it has a wide range of product lines and solutions in the three major fields of complete power transmission and distribution equipment, intelligent power distribution systems, and general contracting of power projects.
Our mission is to empower traditional manufacturing industries through technological innovation, make factories smarter and production more efficient, and contribute to Made in China 2026.
