Testimonials

What our partners say

“

"We have used Brasformer internal current transformers and insulators for over 10 years in our medium voltage shielded panels. The failure rate is zero and mechanical mounting ease optimizes our production significantly."

Eng. Ricardo Mendes Technical Director • TecnoPainéis Switchgears

“

"Brasformer outdoor cycloaliphatic CTs were installed in our billing substations in 2018. They supported sea air and high pollution with excellence without insulation degradation. We highly recommend them."

Eng. Amanda Fonseca Maintenance Manager • GridSul Distribuidora
