Engineering Excellence · Global Partnership

Unisafe air insulated metal enclosed switchgear is one of the main product series of air insulated metal enclosed switchgear of ABB Group. It originates from europe and has a design and production history of more than 30 years. Its main features are as follows:

• Global products with excellent performance
-Implement the unified product standards of ABB Group to ensure that global products have the same excellent performance

• Rich global operation experience to meet different needs of customers

• Compact structure and high space utilization
-The main circuit adopts the design of uniform electric field and composite insulation, which has small overall size and reduces the civil engineering investment of users

• Perfect mechanical safety interlock
-It has perfect "five prevention" mechanical interlocking to prevent misoperation of operators and improve safety level

• High quality material selection and high reliability
-VD4 vacuum circuit breaker is equipped as standard. ABB's well-known vacuum interrupter, cast pole of new generation insulating material and operating mechanism with functional modular design are adopted

• Resistance to internal fault arc class IAC AFLR
-High structural strength, resistance to internal fault arc 31.5kA/1s, meeting IAC AFLR

• Environmentally friendly and reduce carbon emissions
-The production process of PT fixed sealing pole used in VD4 vacuum circuit breaker has no three wastes, the carbon emission is only 40% of that of epoxy resin pole, and the PT material is 100% recyclable and degradable, which is environmentally friendly.

• ABB abilitytm intelligent solution realizes the functions of hidden danger early warning and equipment health management.
