8DJH 36: Gas-insulated medium-voltage switchgear

Why gas-insulated medium-voltage switchgear 8DJH 36?

8DJH 36 switchgear is a factory-assembled, type-tested, 3-pole metal-enclosed single-busbar switchgear for indoor installation. It’s widely used by secondary distribution level-public and industrial energy systems, wind and solar farms and other markets including:

Local ring-main units, customer transfer substations and power supply and public utilities switching substations
Wind, solar and hydroelectric power plants
Water and treatment plants
Airports, train stations and underground stations
High-rise buildings
Data centers

Key benefits

Save costs with a reliable, maintenance-free design

Eliminate maintenance cycles, maximize supply reliability and reduce operating and new construction costs with switching devices, enclosed cable plugs and switchgear vessels designed as sealed pressure systems.

Achieve environmental independence

Protect components with hermetically sealed, stainless-steel switchgear vessels resistant to saline air, humidity, dust and condensation. Prevent foreign object ingress and meet IEC/TS 62271-304 design class 2 requirements.

Add personnel and operational safety

Enable secure operation with metal-enclosed high-voltage parts, including cable terminations, busbars and voltage transformers. Mechanical interlocks and outside access to mechanisms and auxiliary switches provide added safety.

Featured capabilities

Durable, long-term performance

Stainless steel switchgear vessel with welded-in bushings, factory-assembled, routine-tested, earthquake-resistant for electrical connections and mechanical components according to IEC 62271-200, IEC 60068-2-57 and IEEE 693-2018.

Modular panel design

Line up and extend individual panels and panel blocks at will — without gas work on site. Low-voltage compartment is available in three wall- or free-standing overall heights, wiring to the panel via plug connectors.

High-performance SF6 insulation system

Non-toxic, non-flammable, chemically stable SF6 gas supports performance under controlled pressure and temperature conditions within a sealed environment while maintaining extremely low leakage rates for long-term stability.
