The ZW7-36 series 40.5KV 1250A Outdoor high-voltage vacuum circuit breaker is a three-phase, 50Hz AC outdoor switchgear designed for 36 KV power distribution and transmission systems, capable of controlling load currents, overloads, short circuits, and other electrical currents by safely switching them on or off.

In recent years, the engineering construction industry has faced increasing complexity due to societal and economic growth, as well as rapid technological advancements. As a result, there is a growing demand for more compact and intelligent switch equipment that requires less maintenance. Domestic and international manufacturers are actively developing 40.5KV 1600A High Current High Votage Gis Gas Insulated Switchgear (C-GIS), also known as medium voltage gas-filled cabinets, which enclose high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell..

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.

Outdoor transformer oil immersed transformer 10kv 20kv 35kv are a newer type of transformer that boasts a better-designed structure and improved performance. Its three core columns, arranged in an equilateral triangle shape, eliminate any air gaps in the magnetic circuit, resulting in tighter windings. The length of the three magnetic circuits is consistent and shorter, and the cross-sectional area of the core columns is closer to a circle. These design improvements lead to enhanced performance, reduced loss, decreased noise, and a better balance of the three components. Additionally, the third harmonic component is reduced. This transformer is well-suited for use in urban and rural areas, industrial and mining enterprise power grids, and is ideal 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 gear that is low-maintenance and smart. Both local and global switch manufacturers are working on innovative 35KV 1600A Gas Insulated Switchgear Mv Gis, also referred to 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.
