Medium Voltage Cable Drying
CHUNG TIN EQUIPMENT SERVICES COMPANY LIMITED provides medium voltage underground cable drying services (6kV – 22kV – 35kV) for transformer substations, factories, industrial parks, and electrical facilities using underground cable systems.
The service helps remove moisture from cable insulation, restore the insulation performance, and ensure safe energization and long-term stable operation.
⚡ WHY IS MEDIUM VOLTAGE CABLE DRYING NECESSARY?
Medium voltage underground cables may absorb moisture due to:
-
Flooding, heavy rain, or humid soil conditions
-
Improperly sealed cable terminations or joints
-
Long-term operation
-
Improper installation or maintenance
👉 Moisture in cables can lead to:
-
Reduced insulation resistance
-
Partial discharge
-
Risk of ground faults or short circuits when energizing the cable
