Transformer oil duct insulation pressboard strip is made of electrical board in the shape of stripe adhered to DDP paper.
Oil duct strip is made of electrical board in the shape of stripe adhered to DDP. It can be combined closely with transformer coil and make coil possess more excellent mechanical and electrical properties. Oil duct strip is widely used in oil-immersed transformers.
Advantage of Oil Duct Strip
Oil duct strip is applied to the coil of the oil type transformer to provide a channel for cooling the transformer oil circulation. The oil duct strip is used to replace the old electrical corrugated board process, which effectively solves the defects of non-standard thickness, collapse and deformation under pressure of electrical corrugated board, and promotes and improves the reliable operation of cooling function. The oil duct strip process is an advanced technology widely used abroad. The oil duct strip produced by ZTelec Group adopts advanced technology, using high quality imported pulp paperboard, imported pulp base paper and pure epoxy resin DDP production. A large number of products are exported to the European market.
