China 112.5 kva transformer Manufacturer, Supplier, Factory

The 72.5KV Outdoor high-voltage SF6 ceramic column circuit breaker is designed for controlling and protecting 72.5KV transmission and transformation systems. It operates on a three-phase AC 50HZ outdoor high-voltage switchgear and can function and opener group. By utilizing the intelligent arc extinguishing principle of "thermal expansion+auxiliary blowing" and equipped with a CTB-1 operating mechanism, this circuit breaker meets the standards of GB1984-2003 and International Electrotechnical Commission standard IEC62271-100:2001 for High Voltage AC Circuit Breakers.

BWG Photovoltaic grid connected cabinet is an important component that undertakes centralized inverters and step-up transformers or AC combiner box step-up transformers. The incoming line of this photovoltaic grid connected cabinet uses a short-circuit breaker input or direct input, and the output uses a circuit breaker or load isolation switch. The busbar is connected with electroplated or purified wire, and provides secondary lightning protection. The maximum rated voltage of the system is AC690V, and the protection level is | P40 indoors and | P65 outdoors; The cables for secondary measurement and control include cables with a current greater than 2.5mm2, cables with a voltage of 1.5mm2, and cables with a control voltage greater than 1.0mm2. The measuring current transformer is a current transformer of level 0.5, and the measuring current transformer is a current transformer of level 0.25. Relevant functions can also be added according to customer requirements. This product adopts professional electrical design, is simple, beautiful, convenient for on-site wiring and maintenance, and ensures long-term stable operation of the equipment.

In recent years, engineering construction has become increasingly intricate due to the growth of society, the economy, and technology. There is a rising trend towards smaller, smarter switch equipment that demands minimal maintenance. Manufacturers, both local and global, are focusing on the development of the 40.5kv 2000A High Voltage Sf6 Gas Insulated Switchgear, also referred to as gas-insulated switchgear (C-GIS). These switchgears house high-voltage elements like busbars, circuit breakers, isolating switches, and power cables within a protective shell with reduced gas pressure.

KXAYZC-12 Photovoltaic prefabricated cabin for new energy primary and secondary equipment is a product specially designed by our company for the box change equipment used in the northwest and northeast cold desert and harsh environment. In view of the temperature difference in the region (low cold or high temperature), more dust and other special features, the product uses a fully sealed double-layer temperature insulation split box, and the equipment is fully automatic heating and cooling equipment.

The 145KV 3150A Centre-break two post disconnector GW4 disconnector's conductive tube boasts a distinctive aluminum profile structure that enhances heat dissipation and fluid flow. This design minimizes the impact of the skin effect, allowing for. The tube's unique design makes it suitable for specific applications. Our product features state-of-the-art silver dedication to quality. This technology improves the adhesion of the silver plating layer, ensuring it meets standards. With appropriate contact pressure, the wear resistance of the contacts is improved, ensuring the silver plating layer remains intact even after extended use, providing long-term peace of mind. The soft connection, made of copper, features a silver-plated conductive contact surface, ensuring excellent conductivity and strong fluid capacity.

The 40.5KV 1600A Outdoor high-voltage SF6 tank circuit breaker is a customized electrical switchgear designed to disconnect high-voltage electrical paths in emergency situations or for scheduled maintenance. It employs sulfur hexafluoride (SF6) gas as the medium to extinguish electrical arcs and provide insulation, which is safely confined within a sealed enclosure. This particular type of circuit breaker is purposely designed for exterior deployment in electrical substations and power transmission systems.
