What is an electrical switchgear manufacturer? Types of electrical switchgear and their applications Key considerations when choosing a switchgear manufacturer Spotlight on Degatech Electric, a leading China-based electrical switchgear manufacturer
What is an Electrical Switchgear Manufacturer?
Control the flow of electrical power Protect circuits from overload or faults Isolate equipment for maintenance or emergency purposes Ensure the safety of both personnel and infrastructure
Power generation plants Industrial manufacturing Commercial and residential buildings Utility substations Renewable energy systems (solar, wind, etc.) Data centers and transportation infrastructure
Types of Electrical Switchgear
1. By Voltage Level
Low Voltage (LV) Switchgear (up to 1 kV) – Used in buildings, small industries Medium Voltage (MV) Switchgear (1 kV – 36 kV) – Used in factories, utilities, renewable sites High Voltage (HV) Switchgear (above 36 kV) – Used in transmission networks and large substations
2. By Insulation Medium
Air-Insulated Switchgear (AIS) – Uses ambient air; common and cost-effective Gas-Insulated Switchgear (GIS) – Uses SF₆ gas; compact but has environmental concerns Solid-Insulated Switchgear (SIS) – Uses epoxy resin; SF₆-free and environmentally friendly Hybrid Switchgear – Combines AIS and GIS benefits
3. By Application
Distribution Switchgear – For power distribution in buildings or facilities Protection Switchgear – For circuit protection using relays and breakers Control Switchgear – For automation and remote operation
Key Components of Electrical Switchgear
Circuit Breakers (e.g., Vacuum, SF₆, Air, or Oil) Disconnectors & Isolators Current Transformers (CTs) & Voltage Transformers (VTs) Protective Relays & Control Systems Busbars & Insulators Control Panels & Human-Machine Interfaces (HMIs)
