1. Cable Paper(Insulating Kraft Paper)
Description:
Cable paper is made of 100% purity sulfate insulating wood pulp. It is widely used on HV cable, signal cable, electromagnetic wire, transformer, mutual inductor, electric reactor, etc.
Specifications:
Thickness: 50um,80um,130um,150um,180um,200um,300um
Width: 625mm, 980mm, 1920mm(Ribbon is available)
Roll Diameter: 650～1000mm Weight of Each Roll: 220～350Kg
2. Diamond Dotted Paper (DDP)
Description:
This product is made of insulation paper coated by modified epoxy resin in the shape of rhombus. It is widely used for interlayer and turn insulation of oil-immersed transformer and reactors. In the process of coil drying, the agglutinating and solidifying of DDP can bond the coil into a fixed unit. The bonding strength of epoxy resin is sufficient to prevent the displacement of the various layers of the winding in short circuit condition and further ensure the long-term mechanical and electrical properties of insulation structure.
Specifications:
Thickness: 80um,130um,180um,200um,250um,300um
Width: 625mm/980mm (Ribbon is available.)
Roll Diameter: 250～300mm Weight of each roll: 45～60Kg 
3. Oil Strut Belt
Description:
This product is made of electrical board in the shape of stripe adhered to DDP. It can be combined closely with transformer coil and makes coil possess more excellent mechanical and electrical properties. This product can be widely used in oil-immersed transformers.
Package&Storage: Packed in carton. Store in dry and clean room at room temperature. Keep away from sunlight, moisture and fire.The storage period is 12 months. Product specifications are negotiable.
