TECHNICAL OVERVIEW

Primary and secondary GIS platforms for compact distribution.

The LMZ GIS range includes TPR6 PLUS for higher-performance primary distribution and TPR6 families for secondary distribution, using sealed stainless-steel gas compartments and factory-assembled type-tested construction.

PRIMARY DISTRIBUTION

TPR6 PLUS

RATED CURRENT

Up to 2500 A

VOLTAGE RANGE

Up to 40.5 kV

SHORT-TIME WITHSTAND

Up to 31.5 kA

GENERAL FEATURES

Sealed-for-life GIS construction with compact system integration.

Factory-assembled and type-tested gas-insulated medium-voltage construction.

Hermetically welded corrosion-resistant stainless-steel gas compartments.

Vacuum circuit-breaker, switch-disconnector and disconnector module options.

Solid-insulated busbar interconnection outside the gas compartments.

Operating mechanisms remain accessible outside the gas compartment.

Primary and secondary distribution configurations with indoor/outdoor options.

TYPICAL APPLICATIONS

Built for demanding medium-voltage distribution environments.

Power-supply companies, substations and power stations.

Cement, automotive, iron and steel, mining and process industries.

Petroleum, chemical, petrochemical, pipeline and offshore installations.

Wind, emergency-power and traction-power supply systems.

ENGINEERED SELECTION

Switchgear selection starts with the network requirement.

LMZ evaluates service continuity, rated values, fault levels, installation conditions and operating philosophy before defining the appropriate switchgear platform and configuration.
