Ring Main Switchgear

As a procurement professional, you prioritize equipment stability under long-term operation, and Kechang Electric's Ring Main Switchgear (RMS) is designed to meet this core demand through optimized structural and cooling solutions. The product adopts a compact enclosed structure, combined with dual cooling modes of natural air cooling (AN) and forced air cooling (AF) with fans, supporting flexible switching between AN/AF to adapt to different load changes. The scientific ventilation slot design maximizes heat dissipation efficiency, effectively reducing internal temperature accumulation even in high-load operation scenarios. This design not only solves the problem of overheating failure caused by poor heat dissipation in traditional switchgear but also reduces energy consumption of cooling systems. For projects with variable load requirements, this dual cooling design can help you save operation and maintenance costs while ensuring continuous power supply.

For procurement in fields such as hospitals, data centers and commercial buildings, fire safety and insulation reliability are non-negotiable. Kechang Electric RMS adopts Class H (180°C) insulation system, with windings wrapped by Nomex paper and epoxy resin casting process, which has excellent long-term heat resistance and effectively extends the service life of the equipment. The epoxy resin used in the product reaches F1 level flame retardancy, has passed IEC 60076 and UL fire safety tests, and realizes oil-free and leak-free operation, minimizing the risk of fire. At the same time, the high insulation level ensures that the switchgear can operate stably without insulation breakdown even in harsh environments, solving your worries about electrical safety hazards in key areas. We can provide complete fire test reports and insulation performance detection data to support your project compliance verification.

Accurate matching of electrical parameters with project requirements is the key to procurement cost control and operation efficiency. Kechang Electric RMS covers a wide range of rated capacities, including 50kVA, 100kVA, 1000kVA and 2000kVA, with flexible voltage levels to adapt to high and low voltage power supply systems. The product has low impedance voltage, low no-load loss and load loss, and the voltage regulation rate meets IEC standards, ensuring stable voltage output and high energy efficiency. The noise level is controlled within 45–65 dB (adjusted according to capacity), which meets IEC/GB noise control standards and is suitable for indoor installation scenarios with high noise requirements. For projects with special electrical parameter requirements, we can provide professional technical solutions to avoid the problem of mismatched parameters affecting project progress.

Efficient operation and maintenance management is an important demand for procurement professionals to reduce human costs. Kechang Electric RMS is equipped with a complete smart monitoring system, including PT100 temperature sensors and smart thermostats, which can display real-time temperature, automatically control fan start/stop and trigger over-temperature alarms. The fan adopts intelligent control mode, which starts automatically when the temperature exceeds the set value and stops when it returns to normal, saving energy consumption. The product supports remote monitoring through MODBUS/RS485 communication protocol, allowing you to grasp the operation status of the switchgear in real time through the background system without on-site inspection. This smart design solves the problems of high difficulty in manual inspection and delayed fault handling, greatly reducing your operation and maintenance workload and fault handling time.

For projects in different regions and environments, the adaptability and installation convenience of equipment directly affect construction progress and cost. Kechang Electric RMS provides multiple protection levels including IP20, IP23, IP30 and IP44, with strong resistance to moisture, dust and corrosion, and can operate stably in high-altitude and high-humidity areas with an operating temperature range of -25°C～40°C. In terms of installation, the product supports vertical and horizontal installation modes, and provides enclosed, open and box-type designs to adapt to different installation spaces. The overall structure is lightweight with reasonable size, and the installation and maintenance process is simplified; the wiring mode supports copper bar and cable terminal, which is compatible with different project wiring requirements. This design not only shortens the construction period but also reduces the labor and material costs of installation and later maintenance.

Product certification and quality assurance are the core guarantees for procurement risk control. Kechang Electric RMS fully complies with international and domestic standards such as IEC 60076, IEEE/ANSI C57, and has obtained CE, UL and RoHS certifications, meeting the energy efficiency regulations of DOE and EU EcoDesign. The product has an expected service life of 20–30 years, with strict control over partial discharge (PD) level, low failure rate in actual application cases. We provide a 3-year quality assurance policy, and can issue complete quality inspection reports and test data according to your needs. For procurement projects with strict quality and certification requirements, our products can help you pass project acceptance smoothly and avoid risks caused by unqualified products.

Most procurement projects have personalized needs, and the lack of customization capacity often becomes a key obstacle. Kechang Electric has rich experience in customization, which can customize RMS according to your project requirements, including voltage level, capacity, protection level, fan quantity and layout, installation size, wiring mode and temperature control system configuration. Our professional technical team will communicate with you in detail to provide customized solutions that balance performance and cost. In terms of after-sales service, we provide on-site installation guidance, technical training and timely fault maintenance services to solve the problems of difficult installation and inconvenient maintenance after procurement. Whether it is standard products or customized projects, we can ensure the consistency of product quality and service, helping you complete the project smoothly.
