On August 26, 2026, Zhejiang Gangheng Electric Company Limited (GangHeng Electric) completed the shipment of five KYN61-40.5 armored metal clad switchgear units to a customer in Myanmar, marking another overseas delivery of high-voltage switchgear from GangHeng's manufacturing facility in Jiangshan, Zhejiang, China.
The shipment includes 40.5kV KYN61-40.5 draw-out AC metal clad switchgear, a high-voltage switchgear solution designed for 35kV power system applications. The equipment is intended for applications where safe electrical distribution, reliable operation, equipment protection, and convenient maintenance are important requirements.
Five KYN61-40.5 Switchgear Units Prepared for Myanmar Delivery
The five switchgear units were prepared for international shipment at the GangHeng production facility before being dispatched to Myanmar. For overseas power equipment projects, accurate manufacturing, configuration control, inspection, packaging, and delivery coordination are essential parts of the supply process.
GangHeng's project experience includes supplying high-voltage and low-voltage power distribution equipment to customers in China and overseas markets. The company has also supplied equipment to markets including Iran, Kyrgyzstan, Zimbabwe, and Tanzania, supporting customers with different project requirements and power distribution environments.
KYN61-40.5: 40.5kV Metal Clad Draw-Out Switchgear for 35kV Systems
The KYN61-40.5 is an armored draw-out AC metal clad switchgear designed for three-phase 50Hz, 35kV power system applications, with a rated voltage of 40.5kV. According to the product specification published by GangHeng, the switchgear is suitable for power plants, substations, industrial distribution networks, and other power infrastructure applications.
The KYN61-40.5 combines metal-clad construction with a withdrawable circuit breaker arrangement, allowing the switchgear to provide integrated functions for electrical control, protection, and monitoring. Its design includes separate relay instrumentation, circuit breaker, cable, and busbar compartments, with independent pressure-release channels for enhanced operational safety.
Key published specifications include:
- Rated voltage: 40.5kV
- Rated frequency: 50Hz
- Main busbar rated current: 630A, 1250A, 1600A, 2000A
- Circuit breaker rated current: 1250A, 1600A, 2000A
- Rated short-circuit breaking current: 25kA, 31.5kA
- Rated peak withstand current: 63kA, 80kA
- Enclosure protection: IP4X
- Applicable standards: GB 3906, GB/T 11022, DL/T 404 and IEC 60298
The switchgear can also be configured with different circuit breaker solutions according to project requirements. The published product information notes compatibility with domestic ZN85-40.5 vacuum circuit breakers as well as selected SF6 breaker configurations, providing flexibility for different project specifications.
Safety-Focused Metal Clad Construction
For medium- and high-voltage distribution systems, equipment construction and interlocking design are important considerations for operators and project engineers. The KYN61-40.5 uses metal-partitioned compartments to separate the main functional areas of the cabinet.
The product design incorporates five-proof mechanical interlocking, safety flaps, a withdrawable trolley mechanism, and separate pressure-release paths. These features are intended to support safer operation, reduce the possibility of incorrect switching sequences, and improve maintainability during routine operation and service.
The product page also specifies an IP4X enclosure protection rating, while the compartment protection condition changes to IP2X when the cabinet door is open and the trolley is in the test position.
GangHeng Electric: Manufacturing Experience for Global Power Distribution Projects
For overseas buyers, product specifications are only one part of supplier selection. Manufacturing capability, quality management, project experience, and after-sales support are also important factors.
According to its company information, Zhejiang Gangheng Electric Company Limited was established in 2004 and is identified as a National High-Tech Enterprise. Its quality and product qualification portfolio includes ISO 9001, ISO 14001, OHSAS 18001, CQC product certification, high-voltage type test reports, and multiple utility model patents. The company is also listed as a qualified supplier for State Grid and China Southern Power Grid.
GangHeng operates its manufacturing facility in Jiangshan, Zhejiang Province, where production equipment includes CNC punching machines, CNC bending machines, laser cutting equipment, copper busbar bending machines, and related testing equipment.
The company's product portfolio covers high-voltage switchgear, low-voltage switchgear, oil transformers, dry-type transformers, and transformer substations, enabling GangHeng to provide equipment for a range of power distribution projects.
Supporting Customers Beyond Equipment Delivery
GangHeng's service commitments include technical documentation and training, defect and missing-parts response, quality inspection during installation and commissioning, and a 12-month warranty after acceptance. The company also states that it provides continuing support for hidden defects after the warranty period and offers 24/7 field support.
For international customers, this service-oriented approach is important because high-voltage switchgear projects often require coordination between equipment manufacturers, EPC contractors, distributors, and local installation teams.
Another Step in GangHeng's Overseas Switchgear Supply
The shipment of five KYN61-40.5 metal clad switchgear units to Myanmar on August 26, 2026 adds another overseas project to GangHeng Electric's growing international supply experience.
By combining high-voltage switchgear manufacturing, configurable product solutions, documented quality systems, and export project experience, GangHeng continues to support customers looking for reliable 35kV metal clad switchgear, 40.5kV switchgear, and draw-out switchgear for power distribution applications.
