LV Epoxy Monoblocks for oil-filled transformers
Amrest Electricals Limited manufactures LV (low voltage) monoblocks designed for oil-filled transformers. They carry current from the transformer’s low-voltage windings to the external busbars or cables.

Where the monoblock fits
The monoblock facilitates current transmission out of an oil-filled transformer on the low-voltage side.
Engineered for high-demand loads
Voltage class
Designed for low voltage (LV) applications, typically operating up to 1.1 kV and 3.6 kV.
Current range
Engineered for high-demand loads, with ratings usually from 250 A up to 6300 A.
Material
High-grade cast epoxy resin for the body and high-conductivity copper (Cu) for the internal busbars.
Standards reference
Designed with reference to IEC 60137 and BS 2562, and other relevant international electrical standards.
