SOLUTIONS

Gas-insulated switchgear

Gas-insulated switchgear (GIS) is a type of electrical power system that encases switches, fuses, circuits, or breakers in a vacuum-sealed environment to protect the components from damage or harsh conditions. This makes GIS the ideal choice for projects where space is limited or equipment will be exposed to salt, sand, or snow.

The confluence of form and function.

HICO is a world leader of both medium- and high-voltage SF6 GIS, ranging from 24kV up to 800kV. We’re able to customize our designs to meet your operational requirements at a competitive price without sacrificing stability or the safety of your employees.

HICO gas-insulated switchgear solutions.

High- and medium-voltage gas-insulated switchgear

Our GIS utilizes sulfur hexafluoride gas (SF6), which is six times heavier than air, to provide greater insulation properties that protect your electrical systems, extend the useful life of critical components, and reduce operational costs. HICO GIS systems are rated to manage up to 800,000-volt currents.

Mobile gas-insulated switchgear

Mobile GIS systems are self-contained units equipped with high- or medium-voltage GIS substations that can be deployed to pick up the slack in the event that a primary substation goes offline for maintenance, experiences an unexpected outage, or if your current energy systems need supplemental power.

FEATURES

Stable reliability

By insulating our GIS systems in SF6 gas-filled metal enclosures, we’re able to minimize long-term costs and maintain operational efficiency.

Safety

We eliminate safety hazards through earthed enclosures, numerous interlocks, and lockout devices. GIS also has an inherently low center of gravity that increases stability during earthquakes.

Elimination of periodic maintenance

GIS systems significantly reduce maintenance costs and downtime by protecting critical components from contamination and exposure to harsh weather conditions.

Efficient installation

We’re able to assemble GIS systems at our factory and shipment them in one complete bay to dramatically reduce installation time and costs.

Environmental compatibility

GIS systems are ideal for urban and suburban environments thanks to their reduced operational noise levels, elimination of radio interference, and painting of enclosures to blend with their surroundings.
