What temperature grade does oil varnished pure silk belong to? The answer is class A, 105°C.
Oil varnished pure silk is made of refined silkworm silk evenly immersed in oil insulating varnish by drying and used for electrical insulation. Oil varnished silk cloth has certain dielectric properties and mechanical properties, suitable for thin layer insulation or pad insulation with higher dielectric properties in motor and electrical appliances.
Oil insulation varnish cloth: high dielectric type; Good oil resistance, suitable for thin layer gaskets or coil insulation of motors, electrical appliances and transformers working in corrosive environment with transformer oil or gasoline.
Appearance of oil synthet fiber varnish silk: the film should be uniform, free of bubbles, creases, damage and impurities affecting use. Uncoiling should not be damaged by bonding. The tray should be cut neatly and should not be taken off.
Length of oil insulation varnish cloth: 50+10m, 100+10m, each volume should not be more than two sections, the length of each section should be greater than 10m.
Width and deviation of oil varnished pure silk: Mm ≥850, it can be directly cut, oblique cut (generally along 45° Angle) into a width of 15, 20, 25mm and other widths according to user needs. For bands with widths of 100mm or less, the deviation is ±0.5mm; Deviation of ±1% of width for bands over 100mm. Lap length of oblique cut varnished cloth band is not greater than 25mm.
Standard thickness: 0.08mm, 0.10mm, 0.12mm, 0.15mm, 0.17mm, 0.20mm. Thickness deviation: ±0.010-0.015mm
