Product Functions
This switchgear performs critical functions for medium-voltage power systems, including circuit control, protection, and monitoring. It facilitates safe power reception and distribution. Its core component is an integrated vacuum circuit breaker or vacuum load switch, which can reliably connect, disconnect and carry normal current as well as fault current. It supports the formation of various cabinet types (circuit breaker, ring main unit, PT, and isolation cabinets) for comprehensive electrical management.
Applicable Environment
The KGNX-12 operates reliably under specific environmental conditions: an ambient temperature range of -10℃ to +40℃, with daily average humidity ≤95% and monthly average ≤90. Installation elevation should be below 1000 meters. It is suitable for areas with seismic intensity not exceeding 8 degrees. The surrounding environment must be free from severe corrosion, water vapor pollution, excessive contamination, and frequent intense vibration.
Product Highlights
◆Space-Saving Design: Compact footprint saves 58% floor space versus standard KYN 28-12 switchgear.
◆Configuration Flexibility: Can be configured as circuit breaker, ring main, PT, or isolation cabinets using integrated vacuum devices.
◆Integrated & Safe Operation: Features a simplified integrated operating mechanism with reliable five-protection interlocking for safety.
◆Robust Construction: Cabinet is made from high-quality hot-dip aluminized zinc steel, offering high strength and corrosion resistance.
◆Enhanced Usability: Spacious cable room, observation windows, and visible isolation/earthing switch status improve maintenance and safety.
◆Advanced Components: Solid-sealed pole vacuum interrupters ensure high pollution resistance, long electrical life, and broad applicability.
◆Superior Alternative: Effectively replaces or outperforms traditional models like KYN 28, XGN 66, and XGN 15.
Installation Instructions
Prior to ordering and installation, please provide the following information:
◇The main busbar scheme number, single-line diagram, rated voltage, rated current, rated short-circuit breaking current, and the layout plan for the switchgear arrangement.
◇Specific requirements for control, measurement, and protection functions.
◇Detailed specifications and quantities for all major internal components.
◇For busbar bridging between cabinets, provide rated current capacity, span, and height from ground level.
◇Any detailed specifications required for operation in special environmental conditions not covered by standard parameters.
