China Outdoor-rated HV disconnect switch Manufacturer, Supplier, Factory

The 40.5KV 1600A Outdoor high-voltage combination electrical appliances, an outdoor high-voltage electrical appliance, is an efficient solution that combines air insulation with SF6 gas for arc extinguishing. This unit is designed for controlling and protecting three-phase AC 40.5kV transmission and distribution systems, as well as for connecting circuit breakers and operating capacitor banks. Its efficiency makes it ideal for use in urban substations, enterprise substations, and mountain substations with limited land availability, promising to improve your operations.

In recent years, engineering construction has become increasingly complex as society, the economy, and technology have advanced. There is a growing demand for compact switch equipment that requires minimal maintenance and is intelligent. Domestic and international switch manufacturing companies are actively developing the 35KV 3150A Medium Voltage Gas Insulated Electrical Switchgear, also known as gas-insulated switchgear (C-GIS), which encases high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell.

The SC(B) series epoxy resin dry-type transformer has been meticulously designed to prioritize safety. Its flame-retardant, fire-proof, and explosion-proof features ensure the highest level of safety. The encapsulated winding allows for direct installation in the load center, providing a maintenance-free and pollution-free solution. The scientific and rational design, in combination with the casting process, yields a product with lower partial discharge, reduced noise, and superior heat dissipation capacity. When equipped with forced air cooling, it can operate for extended periods under a 125% rated load.

This circuit breaker is a multifunctional low-voltage protection device designed for distribution systems with AC 50Hz, rated voltage below 400V, and rated current below 63A. It is suitable for industrial, commercial, and civilian power networks. Its core functions integrate security protection, equipment protection, and intelligent monitoring, which can significantly improve the reliability and operation efficiency of the distribution system. Core functional highlights: 1. Safety protection 1) Personal safety assurance: Through high-precision residual current detection technology (RCD), indirect contact protection is provided, effectively reducing the risk of electric shock. 2) Equipment and line protection: Integrated overload and short circuit dual protection mechanism, accurately cutting off fault current, avoiding electrical fires and equipment damage. 2. Intelligent monitoring and early warning 1) Leakage pre-alarm function: Real-time monitoring of residual current in the circuit. When abnormal leakage (such as insulation degradation) is detected, an alarm signal is output through a passive normally open contact (dry contact). It can be linked to SCADA, fire protection system or sound and light alarm device without an external power supply to achieve early warning of faults and ensure power supply continuity. 2) Flexible threshold configuration: supports custom setting of leakage alarm values, adapting to sensitivity requirements of different scenarios (such as 30mA/100mA adjustable). 3. Diversified control ability Line and motor control: suitable for occasional switching operations of distribution lines or intermittent start-stop control of small motors, meeting the requirements of nonfrequent operation scenarios. Typical application scenarios: 1) Key power supply areas: places with high requirements for power continuity, such as data centers and hospital IT systems, have alarm nontrip mechanisms to avoid accidental power outages. 2) Equipment protection: Front-end protection for devices such as frequency converters and outdoor electrical cabinets that are susceptible to electrical leakage or environmental impact. 3) Intelligent operation and maintenance: By connecting to the building management system (BMS) through touch signals, remote monitoring and preventive maintenance can be achieved. Product advantages: 1) High reliability: thermal magnetic double trip structure, balancing overload delay protection and short-circuit instantaneous action characteristics. 2) Flexible expansion: an optional communication module, supporting remote status monitoring and fault diagnosis. 3) Easy installation: Standardized modular design, compatible with mainstream rail installation, suitable for compact distribution boxes. Summary: This circuit breaker is designed with the concept of "warning first, safety oriented", which ensures the safety of personnel and equipment while maximizing the stability of system operation. It is the preferred protective device for modern intelligent distribution systems.
