Following a domestic electrical equipment manufacturer’s bulk purchase of a partial discharge withstand voltage and partial discharge integrated testing system, Shanghai DEMIKS Power Technology Co., Ltd. (DEMIKS POWER, website www.demikspower.com ) has once again established a strategic partnership with an authoritative testing institution. A complete set of high-voltage insulation testing instruments has been delivered to the Dongguan Municipal Quality Supervision and Testing Center Laboratory in Guangdong Province and has been accepted and put into operation. This fills the hardware gap in third-party CMA/CNAS type testing for medium and low voltage power transmission and distribution equipment and insulation materials in South China, providing compliant and authoritative testing technical support for thousands of electrical, switch-gear, cable, and insulation material manufacturers in Dongguan and the Pearl River Delta.
I. Qualifications of Partner Companies and Positioning of Testing Services
The Dongguan Municipal Quality Supervision and Testing Center in Guangdong Province is a comprehensive public service platform for quality testing under the Dongguan Municipal Government. It possesses CMA accreditation and CNAS national laboratory accreditation , and has specialized testing laboratories for electrical engineering, insulation materials, and power transmission and distribution equipment. It undertakes third-party type testing, factory sampling inspection, and foreign trade inspection services for power products such as 10kV ring main units, SF6 gas-insulated switch-gear, power cables, insulation boards, insulators, and surge arresters in the Pearl River Delta region. Its test reports are mutually recognized in 45 economies worldwide, making it a core authoritative testing institution for high and low voltage electrical enterprises’ product certification, power grid bidding, and export customs clearance . Relying on Dongguan’s large local electrical manufacturing industry cluster, the center has long undertaken mandatory testing projects such as insulation material breakdown strength, switch-gear power frequency withstand voltage, partial discharge, cable resonant withstand voltage, and transformer induced withstand voltage. It has stringent requirements for the accuracy, stability, standardization, and multi-category compatibility of high-voltage testing equipment. This bulk purchase of the entire DEMIKS POWER series of testing equipment comprehensively upgrades the laboratory’s hardware.
II. List of DEMIKS POWER equipment applications in the Dongguan Quality Inspection Center laboratory (with actual equipment photos)
This procurement covers three major categories : complete machine testing systems, insulation material raw material testing equipment, and general power testing instruments .
The Insulation Material Voltage Breakdown Tester (actual explosion-proof oil tank model) is a core piece of equipment for specialized testing of insulation materials. It is designed to meet the needs of the center’s chemical insulation laboratory, testing the dielectric breakdown strength and voltage withstand durability of epoxy insulation boards, cable insulation films, silicone rubber seals, transformer castings, and switch-gear insulation partitions. The oil-immersed test tank eliminates air flash-over interference, and the explosion-proof safety chamber features a door-opening power-off interlock protection system. It complies with the national standard GB/T 1408.1 for the electrical strength of insulation materials, providing precise data support for incoming material sampling inspection, formula development, and product quality assessment of insulation materials.

This DEMIKS POWER test simultaneously covered two core customer groups: complete electrical equipment manufacturers and national third-party quality inspection agencies , demonstrating the brand’s ability to adapt its high-voltage testing equipment to both factory self-inspection and authoritative type testing scenarios. As the core industrial belt for high and low voltage switch-gear, power cables, and insulation materials in China, the Pearl River Delta region, after upgrading its laboratory hardware, can significantly shorten the type testing cycle for local companies and reduce their costs for cross-provincial testing.
