Operates reliably within a temperature range of -15°C to 40°C.
Daily average RH ≤ 95% (steam pressure ≤ 2.2kPa); Monthly average RH ≤ 90% (steam pressure ≤ 1.8kPa).
Designed for installations at altitudes no higher than 1000m above sea level.
Surrounding air must be free from dust, smoke, corrosive, or flammable gases, steam, or salty fog.
External vibration and land tremors can be neglected. Secondary electromagnetism interference induced in the system must not exceed 1.6kV.
Operation Note: To prevent condensation, heaters must be put into service when the switchgear is in readiness or service conditions. Heat dissipation issues inside the switchgear can be managed via ventilation facilities.
The KYN61-40.5 metal-enclosed switchgear is an indoor power distribution unit utilized by power plants, substations, and industrial/mining enterprises to receive and distribute electricity while providing control, protection, and monitoring functions.
It strictly complies with national and international industry standards, including GB3906-2006, GB/T11022-1999, and DL/T 404-2007, ensuring safety and performance reliability in high-voltage environments.
This air-insulated switchgear is rated for voltage levels up to 36kV (and up to 40.5kV for KYN61-40.5 designs) and supports a rated current of up to 4000A.
A heater is crucial to eliminate internal moisture and prevent condensation, which can lead to flashovers or dielectric breakdown. The heater must be operational when the switchgear is ready or actively in service.
Installation requires an ambient temperature of -15°C to 40°C, an altitude of ≤ 1000m, and clean surrounding air free from dust, corrosive/flammable gases, or salty fog. Humidity must remain under strict safety thresholds (daily average RH ≤ 95%, monthly average RH ≤ 90%).
Heat dissipation inside the switchgear cabinet, caused by operational currents, is resolved through specialized ventilation facilities built within the structural layout.
