Brief Introduction
Insulation Spacers/Block for Oil Immersed Transformer The spacers are made of our imported milling machines, generally have T-shapped spacers, trapezoidal spacer, wedge-spacer, stepped spacer, ect.
1. Insulation spacers
Insulating components are made of 100% Electrical-grade pulp through special designed moulds and processing methods or professional machines, which can ensure application in oil-immersed power transformers for good mechanical strength and insulation property.
