Product Description

LW-35-126 Outdoor High Voltage AC SF6 Circuit Breaker

Introducing the LW36-126/3150-40 Self-Extinction AC Circuit Breaker, an outdoor marvel designed for a broad spectrum of electrical systems. Perfect for installations up to an elevation of 2000m (customizable to 3000m) and operating in ambient temperatures no lower than -40°C, this breaker handles dirtiness grades of IV or below. It supports alternating current at 50Hz with a maximum voltage of 126kV. Ideal for cutting rated currents, managing malfunction currents, and switching circuits, it plays a crucial role in controlling and safeguarding electrical systems. Additionally, it seamlessly integrates with circuit breakers for enhanced operational efficiency.

35-110KV Circuit Breaker
Our SF6 Circuit Breaker leverages SF6 gas as the arc-extinguishing medium and dielectric material, featuring advanced self-extinction technology and a new-type spring operating mechanism. This combination results in a circuit breaker with an extended electrical life, minimal operational power requirements, reduced noise, and superior reliability. Its simple yet robust structure ensures prolonged maintenance intervals and positions it as a perfect replacement for imported counterparts.

 

Characteristic of Structure

The breaker showcases a three-phase porcelain-pole with a single interrupter structure, augmented by a spring operating mechanism. The mechanical actions of the three-phase are interconnected, and the SF6 gas is distributed across the three-phase pole sections. Equipped with a density controller with temperature compensation, it meticulously monitors the SF6 gas. Thanks to the self-extinction arc control principle and optimized design, operational efficiency is maximized, and power consumption is minimized.

Excellent breaking performance and long electrical life.
Crafted with precision, the circuit breaker's metal frame and support are constructed from a single deep-bent steel plate, with hot galvanizing for surface treatment. High-strength stainless steel and aluminum are used for fasteners and the three-phase transmission shaft. The structure box, made from stainless steel, significantly enhances corrosion resistance. The mechanism's high reliability ensures frequent operation, and its high insulation intensity and excellent contact movement prevent re-burning during breaking capacity current.

Boasting high outer insulation levels and a ratio creepage distance exceeding 31 mm/kV, this circuit breaker excels in resisting filth and earthquakes, ensuring safe operation even in harsh weather conditions. Its impressive carrying capacity allows for high capability margins, with minimal temperature rise during tests at 3780A (1.2 times of 3150A). The breaker's compact design simplifies installation and debugging, while its maintenance remains remarkably convenient.
