Engineered to deliver exceptional short-circuit capacity, continuous thermal rating, and rapid transition performance.
In the contemporary digital-first industrial paradigm, the margin for power interruptions has shrunk to zero. Whether driving remote processing stations, hospital life-support apparatus, automated semiconductor fabrication units, or critical municipal infrastructure, power continuity forms the core of operational resilience. Standard municipal grid systems—while structurally robust—remain susceptible to extreme meteorological anomalies, structural network overloads, and dynamic transformer failures. To mitigate these risks, heavy industries implement standby generator systems governed by Automatic Transfer Switches (ATS).
As an industry-leading OEM and ODM partner, Zhejiang Igoye Energy Technology Co., Ltd. (Gongneng Electric) acts as a primary link in the energy value chain. We develop intelligent components including low-voltage distribution frameworks, hybrid isolators, and class-leading ATS modules that facilitate instant, seamless energy transition. Designing custom switchgear necessitates a thorough understanding of electrical topology, interrupt capacities, and the micro-second mechanical timing required to protect delicate equipment from upstream voltage swells.
"Information Gain in Electrical Safety: Modern transfer switch dynamics require a transition from classic mechanical relays to intelligent, solid-state sensing mechanisms. The integration of microprocessor-controlled units prevents voltage drops during phase transition, lowering systemic stress on downstream hardware by up to 35%."
Demystifying the switch configurations that safeguard systems under severe overload scenarios.
Understanding transfer topography is vital. Class CB ATS units are equipped with overcurrent releases, enabling their main contacts to trip and clear short-circuit faults. Class PC units utilize a simpler mechanical construction designed specifically to carry and transfer currents but not clear system faults, relying on external MCCB protection. Igoye manufactures both variants to optimize design cost and fault ride-through capacity.
Our intelligent MCCBs and ATS frames feature high interrupting capacities (Icu up to 150kA at 400V). Using advanced silver-alloy contacts and specialized arc-chutes, they extinguish high-energy electrical arcs in milliseconds, ensuring complete isolation of the damaged electrical branch and securing secondary bus-bars.
Integrating generators with non-linear industrial loads induces harmonic distortions. Igoye's GNCS Integrated Smart Capacitors stabilize the voltage profile, compensate reactive power in real-time, elevate the power factor above 0.95, and relieve downstream stress on switching mechanisms.
How Yueqing's high-density component ecosystem enables Igoye to deliver robust manufacturing and engineering speed.
Located in the heart of Yueqing's Economic Development Zone in Zhejiang Province, Igoye enjoys immediate proximity to the Qili Harbor in the south, Yueqing Bay in the east, and the Liubai economic corridor in the west. This geographical positioning offers access to one of the world's most dense clusters of high-quality raw materials, copper foundries, silver contact manufacturers, and precision plastic injection facilities.
By leveraging this local supply chain network, we reduce lead times by up to 40% compared to isolated manufacturers. We employ a strict Statistical Process Control (SPC) regime at critical stages. Each incoming shipment of steel, copper, and engineering plastics undergoes spectrometer verification, while our complete traceability program associates every finished circuit breaker and transfer switch with its production run date, operator, and raw material batch number.
Specialized low-voltage and ATS systems designed for challenging operating environments.
Our solutions feature smart motor protection to prevent pump tripping during high-torque startups. If main power drops, our dual power transfer switches execute a high-speed changeover to preserve generator power, maintaining process flow. Integrated smart capacitors optimize power factors and lower losses.

Expert answers to common engineering questions about transfer switches and circuit breakers.
Class CB switches are built with a trip mechanism and overcurrent releases, allowing their contacts to open to clear short-circuits. Class PC switches are designed to carry and transfer current but do not clear faults, relying on upstream circuit breakers (like MCCBs) to handle short-circuit protection.
Backup generators can experience voltage fluctuations and high harmonics from industrial loads. Smart capacitors (such as our GNCS models) compensate reactive power in real time, stabilizing the voltage profile and keeping the power factor above 0.95 to protect switching systems.
Our quality control program uses Statistical Process Control (SPC) at key manufacturing steps. Incoming components are verified for material composition, and finished circuit breakers and switches undergo full dielectric strength, timing verification, and mechanical cycling tests before shipment.
