What is a Shell Type Transformer?
Shell Type Transformer Definition
A shell type transformer is defined as a transformer with a magnetic core using ‘E’ and ‘L’ shaped laminations.
Core Structure
The core has three limbs, with the central limb carrying all the flux and side limbs half the flux, enhancing strength and protection.
Winding Design
HV and LV windings are alternately wound around the core, needing less conductor but more insulation.
Cooling System
Requires forced air and/or oil cooling to dissipate heat effectively from the windings.
Advantage
Low cost
High output
Disadvantage
Manufacturing is complicated
Labor costs are high
Applications
Shell type transformers are used for low voltage applications and help optimize circuit expenditure.
