Description
Premium Duct Strip & DPP Paper for Transformer Insulation
Duct Strip & DPP Paper are essential transformer insulation materials used to improve cooling efficiency, electrical insulation, and mechanical stability within power and distribution transformers. Duct Strips create oil circulation channels between transformer windings, while DPP (Diamond Pattern Paper) provides excellent electrical insulation and strong bonding between winding layers during the transformer manufacturing process.
At Star Group of Companies Caribbean, we supply premium-quality Duct Strip & DPP Paper in Trinidad and Tobago, manufactured from high-grade electrical insulation materials to deliver outstanding dielectric strength, thermal stability, and compatibility with transformer insulating oil. These products help improve transformer cooling, minimize electrical stress, and enhance the overall reliability and lifespan of transformer windings.
Designed to meet international transformer industry standards, our Duct Strip & DPP Paper solutions are ideal for transformer manufacturers, utility companies, repair workshops, and industrial applications throughout Trinidad and Tobago and the wider Caribbean.
