Zw7-40.5 Series Outdoor High Voltage Vacuum Circuit Breaker, 35kv Transmission and Distribution System

Product Description

ZW7-40.5F(M) Outdoor High Voltage Intelligent (Permanent Magnet) Vacuum Circuit Breaker
Product Overview
The ZW7-40.5F(M) is an outdoor high-voltage intelligent vacuum circuit breaker designed for medium-voltage overhead power lines. It integrates split-pole structure with a highly reliable spring or permanent magnet operating mechanism, enabling efficient load current switching, overload protection, and short-circuit interruption. Ideal for smart grid applications, it ensures reliable power distribution and system stability.
Key Features and Applications:
1. Innovative Design
• Utilizes split-pole structure combined with spring or permanent magnet operating mechanisms for enhanced reliability and reduced maintenance.
• Compact modular design simplifies installation and adapts to diverse grid configurations.
2. Smart Functionality
• Supports remote control and automation integration, compatible with distribution automation systems for rapid fault isolation and power restoration.
• Equipped with intelligent controllers for real-time monitoring and data analysis to optimize grid performance.
3. Robust Environmental Adaptability
• Corrosion-resistant steel enclosure ensures durability in harsh outdoor conditions (e.g., humidity, temperature extremes).
• High seismic resistance, compliant with seismic intensity requirements up to magnitude 8.
4. Versatile Applications
• Suitable for substations, industrial plants, and urban/rural distribution networks for line protection and control.
• Ideal for frequent operation scenarios, including ring main systems, branch lines, and user responsibility demarcation points.
Combining reliability, intelligence, and flexibility, this product delivers a secure and efficient solution for modern power transmission and distribution systems.
Standard Specification
(It can be customized according to customer's local demand!)
1. Technical parameter table:
The ZW7-40.5F(M) circuit breaker supports a maximum voltage rating of 40.5kV, combining 1250/1600A rated current and 25/31.5kA short-circuit breaking capacity with dual operating mechanisms (permanent magnet/spring) to deliver reliable protection for medium-voltage grids. Customization options span all core parameters: Current & Breaking Capacity: Support for extended rated current and higher short-circuit breaking capacities (e.g., 40kA); Operation & Control: Optional spring mechanism instead of permanent magnet configuration, compatible with multiple voltage control requirements such as DC 110V/220V; Functional Expansion: Addition of disconnectors and built-in voltage transformers for comprehensive grid monitoring and protection; Environmental Adaptation: Custom solutions for high-altitude (>1000m) and high-pollution (Class IV) environments ensure stable operation in harsh conditions. Backed by over 30 years of experience in power equipment R&D, our technical team responds rapidly to customer needs, leveraging modular design and rigorous validation processes to ensure reliability and cost-effectiveness of customized solutions. This empowers clients to maintain a competitive edge in smart grid development.
