GENERAL CHARACTERISTICS:-

  • MAGIS 36 is a metal enclosed switchboard with standardized units for public, private, industrial medium voltage electrical distribution system.

  • The "MAGIS 36" series employees on high performances SF6 insulated Load Break Switch (our G type) is a 3 position type (closed, open, earthed) in a cast resin envelope which is internal arc proof.

  • The use of a resin envelope gives remarkable advantages from the dielectric and mechanical points of view.

  • Breaking capacity of no load cables-  16 A

FAQs

metal enclosed switchgear?

Metal-enclosed switchgear is defined in ANSI C37. ... This essentially describes non-compartmentalized metal-enclosed single or multiple fused or non-fused load interrupters such as Eaton's type WLI.

Can metal clad switchgear be considered as metal enclosed?

Since metal clad switchgear (IEEE C37. 20.2) is technically a subset of metal enclosed, it shares many of the same external properties. It is enclosed in a metal shell on all sides, with the exception of small ventilation and viewport openings

What are the different types of switchgear?

Types of medium-voltage switchgear

  • Gas-insulated switchgear. 

  • Metal-clad switchgear. 

  • Metal-enclosed switchgear. 

  • Pad-mounted switchgear. 

  • Vault or subsurface switchgear.

What are switchgears used for?

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.
