Coatings for power equipment — GIS, transformers, control cabinets (SF₆ resistance, ATEX, conductive and insulating)

Technical specifications

Specifications are taken from the manufacturer’s technical documentation. Updated 11/10/2026.

Description

The objects need protection against corrosion, climatic effects, chemical and electrical loads, including in extreme conditions. SF₆ resistance is confirmed in high-voltage installations and switchgear, and there are also versions for alternative insulating gases. For outdoor installation the coatings are resistant to UV and condensate, and the anticorrosion protection is selected individually and confirmed by salt spray testing. By application technology, single-layer systems, water-based formulations, materials with low, medium and high solids, VOC-optimized and fast-drying ones are available, which work well at low temperatures and reduce energy costs for drying. Small batches and a wide color palette for equipment series are possible. For GIS and transformers above 1 kV the coating goes to the manufacturer as a material, so this item belongs to paint chemistry. Specific grades and binders are not disclosed in the open data.

How to choose

First determine the function: whether a conductive or insulating coating is needed, and whether ATEX compliance and SF₆ resistance are required. Then the application technology is selected, single-layer, water-based or VOC-optimized, depending on the line and drying temperature. The specific product for a project is selected by the Technical Service Center (TSC) in Hamburg, which advises on both requirements and design.
