Application of crepe paper: Transformers: This crepe paper is used as an insulation in manufacture of oil cooled transformers, current transformers of types imb, ct, cvt, etc. As leads and shields. This crepe paper has 300% more strength in mechanical and cross mechanical directions and hence is more resistant to breakage. It can also take various shapes of the surface being insulated. Crepe paper also has greater surface area which helps to retain more oil and hence lowers the working temperature of the transformer. Crepe paper covered copper conductors for transformers: This crepe paper is used to cover copper conductors having various cross sectional shapes. This paper is used to cover copper conductors bent at an angle of 180o. As a result this insulation will not break or tear or crack compared to plain kraft paper insulation. Availability: The base kraft paper thicknesses on which creping is done are 1.5mil (40microns), 2.0mil (50 microns), 2.5mil (65 microns), 3.0mil (75 microns), 4mil (100 microns), 5.0mil (125 microns). Thickness above 5 mil can be provided as per customer’s requirement. The elongation can be supplied as per specification from 10% up to 300 %. This crepe paper can be supplied in jumbo rolls of 1000mm (1 meter) width or in slitted pads as per customer requirements. As per requirement

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: 650ï½?1000mm Weight of Each Roll: 220ï½?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: 250ï½?300mm Weight of each roll: 45ï½?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.

Cyan / Highland barley paper insulation paper material Green shell paper, also known as highland barley paper, is a common name for blue thin electrical insulating cardboard. Made from a mixture of wood fibers or cotton fibers and processed through certain processes, the green shell paper combines the excellent insulation performance of wood pulp insulation paper and the good dielectric strength of polyester film. The commonly used colors for thin electrical insulating cardboard are yellow and cyan, commonly known as yellow shell paper and cyan paper. Highland barley paper is processed with 100% wood pulp and has good electrical and mechanical properties. It is widely used as an insulation material in motors, appliances, instruments, and switches. It can also be used in 6520 polyester film composite foil base paper. The thickness of the cardboard is 0.1mm-0.5mm, and its colors include natural color, green shell color, red, blue, yellow, and so on. Characteristics and usage: Green shell paper has good mechanical strength, high electrical strength, flat and smooth surface, and high toughness. It is widely used as an insulation material in equipment such as motors, electrical appliances, and instruments. It is also used for slot to slot insulation, turn to turn insulation, and pad insulation of B-class motors. Simultaneously used for making 6250 polyester film composite foil. Use screws to fasten the wings and heads of a ceiling fan for home use, with a layer of green shell paper spaced between them.
