Revolutionizing Medium-Voltage Distribution with Vacuum Circuit Breakers and Solid Insulated Switchgear

Introduction

Medium-voltage power systems form the backbone of industrial, commercial, and utility networks. As the demand for electricity grows, maintaining safe, reliable, and environmentally friendly distribution becomes paramount. Among the key components driving modernization are vacuum circuit breakers (VCBs) and solid insulated switchgear (SIS).

VCBs and SIS work together to deliver high-performance, low-maintenance solutions for 12kV/24kV and higher voltage systems. Degatech Electric Co. Ltd. provides a complete portfolio of these components, enabling distributors and engineers to upgrade infrastructure with confidence. Learn more at https://chinadegatech.com/.

Understanding Vacuum Circuit Breakers

What is a Vacuum Circuit Breaker?

A vacuum circuit breaker interrupts current flow in medium-voltage circuits by separating contacts in a vacuum chamber. This prevents arcing and allows fast, reliable fault clearance. Key advantages include:

Compact size and lightweight design

High electrical endurance with minimal maintenance

No need for insulating gas like SF6, making them environmentally friendly

Exceptional operational reliability under high-load conditions

VCBs are widely used in ring main units (RMUs), industrial substations, and GIS, providing essential protection for transformers, feeders, and distribution lines.

Features of Modern VCBs

High Breaking Capacity – Handles short-circuit currents up to 31.5kA

Long Mechanical Life – Capable of over 10,000 operations without significant wear

Integration Ready – Compatible with SIS and IoT monitoring modules

Environmental Safety – Free from harmful gases, fully recyclable components

Applications

Substations (12kV/24kV)

Industrial and commercial power centers

Renewable energy integration points

Urban distribution networks

For distributors, highlighting maintenance-free, safe, and reliable performance is a strong selling point.

Solid Insulated Switchgear (SIS)

Overview

Solid insulated switchgear integrates busbars, vacuum circuit breakers, and protective relays within a polymer-encapsulated enclosure. This design reduces footprint, improves safety, and simplifies maintenance.

Benefits of SIS

Compact and Modular – Perfect for urban or industrial areas with space limitations

Reduced Maintenance – Encapsulation protects against dust, moisture, and corrosion

Enhanced Safety – Minimizes the risk of electrical shocks and fire hazards

Environmental Friendly – No SF6, reducing greenhouse gas emissions

Scalable – Easy to expand networks without replacing existing units

Combining SIS with VCBs delivers a complete, modern solution for medium-voltage systems.

Epoxy Resin Bushings in Modern Systems

What They Are

Epoxy resin bushings serve as insulated passageways for conductors through grounded barriers. They offer:

High mechanical strength

Excellent insulation under voltage stress

Resistance to moisture, dust, and pollution

Lightweight and compact design for easy installation

Advantages Over Traditional Bushings

Reduced footprint compared to porcelain alternatives

Lower maintenance and operational costs

Environmentally safe, free from lead and toxic substances

Ideal for RMUs, GIS, and industrial power systems

Distributors can use epoxy resin bushings to enhance the reliability and durability of their medium-voltage projects.
