Description:

XGN£-12 type Solid Insulated Ring Main Unit switchgear (Solid Cabinet for short) is a switchgear which uses solid insulated materials as main insulating medium. Connect the vacuum arc-extinguishing chamber with its electric conduction, disconnector, grounding switches, main bus, branch main bus and other dominant electric circuits. After single or combination, cover it with insulated solid medium as one or multiple functional, recombinational or extensible models with full insulation or full airtightness. The solid cabinet is a new generation of environmental-friendly composite insulated, fully sealed power supply unit. It’s not affected by the external environment, effectively ensuring operational reliability, personal safety and maintenance-free.

Features:

u Environmental-friendly solid insulated materials: good environmental protection, maintenance-free, reliable insulation performance and strong environmental adaptability.

u Modular design: small in size and convenient for on-site assembly especially for remote areas.

u Complete mechanical interlock function, fully meeting interlocking protection requirements.

u Compact size, easy to install and easy to operate with expandable modular combination. Choosing the best wiring scheme according to customer needs.

u Side or side expansion depending on the installation location.

u Configuring electric, remote control and monitoring devices with simulating the different needs of users.

u Complete and reliable Five-protection system.

Using environment:

u Temperature: -10℃~+25℃ indoor, -60℃~+60℃ outdoor;

u Relative humidity: Daily average ≦95%; Monthly average≦90%;

u Altitude: ≦3000m;

u Shock level: Horizontal acceleration 0.4m/s2,Vertical acceleration 0.15m/s2;

u Installation location: The place with no severe impact, serious pollution and chemical corrosion, no conductive dust and explosion risk.

When the conditions of use exceed the above range, the user shall negotiate with us to determine the allowable range or take corresponding supplementary technical measures.
