Product Introduction
IEE-Business 10kV Normal Pressure Sealed Air-Insulated Switchgear/Ring Main Unit (single circuit) ya nuna clean da dry air don insulation medium, wanda yana taka cewa ba a gaji da SF₆ gas, wanda yake da shiga tsakanin ita ce, amma kuma yana taka karfi da kyau da cost of operation and maintenance. Da ake yi design da fully sealed structure, yana iya inganta dust, moisture, and corrosive gases na fasahar, wanda yake da shiga tsakanin ita ce, amma kuma yana iya inganta dust, moisture, and corrosive gases na fasahar, wanda yake da shiga tsakanin ita ce, amma kuma yana iya inganta dust, moisture, and corrosive gases na fasahar, wanda yake da shiga tsakanin ita ce. Configuration na single-circuit yana da shiga tsakanin ita ce, amma kuma yana da shiga tsakanin ita ce, amma kuma yana da shiga tsakanin ita ce, amma kuma yana da shiga tsakanin ita ce, amma kuma yana da shiga tsakanin ita ce. Cabinet yana da shiga tsakanin ita ce, amma kuma yana da shiga tsakanin ita ce, amma kuma yana da shiga tsakanin ita ce, amma kuma yana da shiga tsakanin ita ce. It is widely used in incoming line, feeder and ring network connections of 10kV power distribution systems in urban distribution networks, industrial parks, residential communities, etc., providing safe, stable and environmentally friendly operation guarantee for power distribution networks.
Normal pressure sealing: No leakage risk, ensuring excellent insulation performance.
Air insulation: The gas requires no treatment. Through improved processing techniques, selection of high-grade materials, and optimized electric field design, it meets the demand for miniaturization.
Simple operating mechanism: With a simple and stable structure, its mechanical service life can reach 10,000 times.
Miniaturization: Its volume is 1/5 that of KYN, equivalent to the volume of conventional pressure-type ones, saving space.
Standardized expansion method: Facilitates on-site installation and reduces power outage time.
