product description
Product introduction
Oil strut belt for transformer is made of electrical board in the shape of stripe adhered to DDP(Diamond Dotted Insulating Paper).It can be combined closely with transformer coil and makes coil possess more excellent mechanical and electrical propeties.It is widely used in oil-immersed transformers.
Key Features
Type: Insulation Paper, Insulation Materials
Thickness: 0.1-0.5mm
Desity: 1.10-1.15g/cm3
Width: 980mm
1.High Purity and oil absorption.
2.Good compatibility with liquid dielectrics strength.
3.The combination with transformer coil is very firm, also can avoiding the traditional variability and easy displacement of corrugated cardboard, which make this coil has more excellent mechanical and electrical properties and widely used in oil-immersed transformers.
