China transformer yard Manufacturer, Supplier, Factory

The outdoor oil-immersed transformers at 10kV, 20kV, and 35kV levels have an advanced design with improved performance characteristics. They feature a unique structure with three core columns arranged in an equilateral triangle configuration. These gaps within the magnetic circuit, along with a core column loss, help reduce noise levels and ensure better balance of the transformer components. Additionally, these transformers effectively minimize the presence of the third harmonic component. They are suitable for various applications, including urban and rural areas, industrial and mining power grids, and are particularly well-suited for combination transformers and pre-installed substations.

In recent years, with the progress of society, economy, and technology, engineering construction has become increasingly intricate. There is a rising demand for compact switch equipment that is low-maintenance and smart. Domestic and international switch manufacturers are working on 12KV 3150A Medium Voltage Electrical Switchgear Gas Insulation Switchgear, known as gas-insulated switchgear (C-GIS). This type of switchgear encases high-voltage elements like busbars, circuit breakers, isolating switches, and power cables in a shell with reduced gas pressure..

Its integrated trip mechanism combines residual current detection (≤30mA sensitivity) and instantaneous magnetic tripping, effectively isolating faults while maintaining a secure operational environment. Wide Application Scope: Designed as a versatile miniature circuit breaker (MCB), it supports 1P+N, 2P, 3P, 3P+N, and 4P configurations, accommodating diverse electrical networks ranging from residential single-phase systems to industrial three-phase installations. The modular design ensures compatibility with global wiring standards, making it ideal for panel builders and system integrators. Durability & Cost Efficiency: Engineered with industrial-grade thermoplastics and silver-alloy contacts, this ELCB guarantees a minimum service life of 20,000 mechanical operations under IEC 60947-2 compliance. Backed by a 2-year warranty, its maintenance-free design reduces downtime and lifecycle costs, offering exceptional long-term value. Global Compliance: Certified to IEC 61009-1 (RCCB) and EN 60898-1 (MCB) standards, the device meets stringent international safety and performance requirements. Its universal design ensures seamless integration into both 50Hz and 60Hz grids, aligning with regional regulations across 230V/400V markets in Asia, Europe, and beyond. Customization Flexibility: Users can select optimized configurations for frequency (50Hz/60Hz) and voltage ratings (230V/400V), enabling tailored solutions for HVAC systems, machinery control panels, or renewable energy installations. Optional auxiliary contacts and shunt releases further enhance adaptability to complex automation scenarios.

The CFB3 series miniature circuit breaker is suitable for overload and short circuit protection in AC 50/60Hz, rated voltage up to 230V/400V, and rated current up to 125A lines. It can also be used for infrequent on/off operations of the line under normal conditions. The CFB3-63 series circuit breaker is equipped with accessories such as CFB3-F auxiliary contacts, CFB3-FB auxiliary alarm contacts, CFB3-FL shunt release, CFB3-QY undervoltage release, CFB3-GY overvoltage release, CFB3-GQY overvoltage release, etc., providing convenience for the intelligent control of smart buildings. Overvoltage, undervoltage, and overvoltage/undervoltage are electronic release devices that are assembled and combined with circuit breakers or residual current circuit breakers. They are suitable for AC 50Hz/60Hz circuits with a rated voltage of 230V, and are used to protect against overvoltage, undervoltage, and overvoltage caused by line faults, avoiding damage to electrical equipment or inability to function properly due to fluctuations in grid voltage. The circuit breaker has an isolation function. Compliant with standards: GB/T10963.1, IEC60898-1, GB/T20645.

The KYN28-12(Z) AC metal-clad switchgear 7.2KV 2500A High Current Electrical Switchgear is designed for use in 12kV-rated three-phase AC power systems operating at a frequency of 50Hz. It is utilized for the reception, distribution, and monitoring of electrical energy, as well as for circuit control and protection.
