What is 35kV High Voltage Switchgear?
35kV High Voltage Switchgear is a compact metal-enclosed system that integrates circuit breakers,
disconnectors and protection devices to control, protect and isolate electrical equipment.
Designed for medium voltage applications, it is a critical node in the distribution network,
ensuring stable power delivery from the substation to the end user.
Key Features and Benefits
Double Insulation: Combines SF₆ gas or solid insulation to minimize arc flash risks.
Five-fold Protection Mechanism: Prevents accidental operation (such as on-load closing) through an interlock system.
Corrosion-resistant materials: Galvanized steel or stainless steel cabinets withstand humidity, dust and temperature fluctuations (-25°C to +40°C).
Seismic Resistance: Suitable for use in earthquake zones to ensure stability even in unstable ground conditions.
Remote Control: Compatible with SCADA systems for real-time status checks and fault diagnosis.
Condition-Based Maintenance: Sensors track temperature, humidity, and partial discharge to prevent failures.
Sulfur Hexafluoride (SF₆)-Free Options: Optional dry air or environmentally friendly gas insulation to reduce the greenhouse effect.
Low Energy Consumption: Optimize energy efficiency without compromising performance.
