Haitan Electromechanical Technology Co., Ltd., located in Liushi Town of Leqing City, the electrical capital of China, is mainly committed to the research and development and production of insulation accessories for complete sets of cabinets and energy storage new energy insulation parts. Especially, our products like busbar clamps, State Grid SLVA busbar clamps, busbar terminals, live display lighting lamps, high and low voltage insulators, heat shrink tubes, and cable ties have been well praised by customers.

Over the past more than 30 years, the company has continuously improved the level of technology and process equipment, the technical renewal and transformation, accumulated rich experience in production management and industry-leading technology; Also, through establishing the advanced professional laboratories equipped with multifunctional Withstand Voltage/ Insulation Tester, and related equipment of combustion detection engine, the company has always kept pace with the times, maintained core competitiveness and brand advantage, and written a chapter of well-grounded development.

Along the way, the company, with a long-term vision and pursuit, has achieved a balance between domestic and foreign trade. As the first enterprise in the industry to pass the national CQC certification and the requirements specified by the State Grid, and one of the few enterprises in the industry that meet the ISO9001, ISO45001, and ISO14001 certifications at the same time, the company has obtained a number of test reports and 13 patents for utility models and design for busbar insulation frames and insulators. Over these years, the company has served more than 30 countries around the world and her influence keeps improving.

We are keenly aware that management is the soul of development. Therefore, through flat management, the company always insists on decentralization, breaks down information barriers, coordinates internal management software to empower and give full play to team advantages, takes customers as the center, responds quickly to their needs, and provides professional customized production services.

Inclusion, openness and customer orientation are always the principles that our company abides by. In the future, we will always adhere to our original aspiration and our goal (high quality and high precision), continue to forge ahead, innovate and strive to maximize customer value, and continuously provide high-quality and high-performance products for global customers.

For three decades, our mission has remained unchanged: to make every electrical connection safer, more reliable, and more durable. From early product development to today’s advanced manufacturing, we have consistently prioritized quality, safety, and engineering excellence.

Standing on 30 years of quality heritage, we continue to innovate and refine insulation technologies—ensuring stable performance across industrial, commercial, and energy-critical environments.

Among our extensive product lineup, the SMインシュレーター そして SBインシュレーター Series represent our unwavering commitment to safety and long-term reliability. Engineered for extreme conditions and precision applications, these two series have become trusted choices for electricians, contractors, and system integrators worldwide.

Why Insulation Matters: Safety Built Into Every Connection

Electrical systems face constant threats:

High voltage stress

Environmental moisture

Mechanical vibration

Temperature variations

Aging and corrosion

A high-quality insulator is the first line of defense. It prevents leakage currents, avoids energy loss, and protects both equipment and human operators from electrical hazards.

For 30 years, we have refined our insulation materials, molding processes, and structural designs to deliver superior dielectric strength, mechanical stability, and long service life.
