RESIBLOC® cast-resin transformers offer maximum mechanical strength to withstand thermal and mechanical stresses from severe climates, cycling loads, and short circuit forces. RESIBLOC transformer windings are hermetically cast in epoxy without the use of a mold for maximum design flexibility. RESIBLOC transformers are non-explosive with high resistance to flame and do not require vaults, containment dikes, or costly fire suppression systems.

RESIBLOC transformers are produced in full compliance with DIN EN ISO 9001, DIN EN ISO 4001 and BS OHSAS 18001 standards.

The material Resin is a material of immense strength.

Modern winding processes, combined with electronically controlled winding machinery, ensure an even distribution of glass fibre rovings and epoxy resin, and the highest precision in the manufacture of transformer windings. Multi-spaced ribs, built-in during the winding process, integrate the HV and LV windings into a single compact winding block. No risk of any contamination to the application environment and non-explosive with high resistance to flame. Severe load cycles (cold start to maximum load) and high short circuit withstand. Exposure to harsh climates (freezing, heat, chemicals, moisture); minimal maintenance.
