Insulating material: Insulating laminate

transformer pressboard are also known as laminates, and there are many types of insulating laminates, including phenolic cotton laminates, epoxy glass cloth laminates, insulating paperboard, silicone glass cloth laminates, melamine glass cloth laminates, diphenyl ether Glass cloth laminates, bismaleimide glass cloth laminates, polyimide glass cloth laminates, graphite glass cloth laminates, high strength epoxy glass cloth laminates, etc., referred to as insulation board.
With the development of the electrical industry, high insulation. High strength, high temperature and adapt to a variety of use of laminated plastic products have emerged. Printed copper clad laminates for printed circuits are also rapidly evolving due to the needs of the electronics industry. China's electrical and epoxy fiberglass tube are gradually developed after the liberation. China's thermosetting laminate has formed a relatively complete series.

Flame retardant cable commonly used insulating materials and the main performance

The performance of the flame retardant cable is determined by the oxygen index of the mica insulation sheets used, and the higher the oxygen index, the better the flame retardant performance of the flame retardant cable. But at the same time will lose part of other performance, increase the difficulty of operation and material costs.
Flame-retardant cable through the standard clock C class experimental requirements on the requirements of the oxygen index of vulcanized fiber sheet to 30, and if you want to achieve Class B and Class A sheathing materials and fillers are used flame retardant materials.

Application of insulating materials

The role of electrical insulating board is in the electrical equipment to the potential of different charged part of the isolated. Therefore, the insulation material should first have a high insulation resistance and pressure strength, and to avoid leakage, breakdown and other accidents. Second, the heat resistance is better, to avoid long-term overheating and aging deterioration; In addition, there should be good thermal conductivity, resistance to lightning and high mechanical strength and ease of processing and so on. According to the above requirements, commonly used laminated compressed wood performance indicators are dielectric strength, tensile strength, specific gravity, expansion coefficient.
Electrician commonly used insulating materials according to their different chemical properties, can be divided into inorganic insulation materials, organic insulation materials and mixed insulation materials. Commonly used inorganic insulation materials are:EPGC203 mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly used for electrical, electrical winding insulation, switch the bottom plate and insulators. Organic soldering frames are: shellac, resin, rubber, cotton yarn, paper, linen, rayon, etc., mostly used to manufacture insulating paint, winding wire insulation and so on. Mixed insulation materials for the above two kinds of materials from the processing of various molding insulation materials, used as electrical appliances of the base, shell and so on.

GPO-3 is a good insulation transformer pressboard, is widely used in the machinery and electrical industry, then it is what good product performance, to win everyone's widely used? The following GPO-3 manufacturer for you!
First, with flame retardant: Because GPO-3 anti static plastic sheet is not halogen-containing materials, so when the phenomenon of fire, it has good flame retardant properties, and will not produce toxic gases.
Second, the product mechanical properties: Because GPO-3 production of the main material is high-strength glass fiber, it is not easy to break the phenomenon, and easy to bend to a diameter of 19mm.
Third, the resistance to high temperature: Because of the special properties of the production of materials, GPO-3 it can 120-210 ℃ electrons and 130-210 ℃ mechanical range with UL temperature rating. With superior stability.
Fourth, good insulation performance: it is high-quality phenolic paper sheet, is widely used in the electrical industry
Fifth, the production of simple and easy to shape: GPO-3 insulation material processing is simple and convenient, can stamping, drilling, machining, cutting and scrub.

bakelite electrical insulation board is a high-performance insulating material, it is also known as epoxy glass fiberboard, epoxy phenolic laminated glass cloth and so on. Epoxy board is mainly composed of: glass fiber cloth with epoxy resin bonded by heating and pressing production, so excellent performance, many advantages. And in what kind of temperature environment can play their own characteristics.
For example, in the medium temperature, can play a good mechanical properties; in high temperature environment, can better play its electrical. Therefore, due to these characteristics, epoxy board is very suitable for electrical and electronic fields of high insulation structure parts. All in a word, that is, epoxy board with high mechanical and dielectric properties, with good heat resistance and moisture resistance. Epoxy board insulation cable paper in the high temperature level in the F-class, which can withstand the high temperature of 155 degrees, in such a high temperature is still to maintain a stable performance.
Its specification thickness is generally between 0.5 ~ 100mm. Commonly used product specifications are 1000mm * 2000mm. Epoxy plate laminated mica sheet at 180 degrees under high temperature will be deformed, so it is generally not used together with other metal heat, or may lead to thermal deformation of metal sheet.

Electrician commonly used fire resistant cables tape according to their different chemical properties, can be divided into inorganic insulation materials, organic insulation materials and mixed insulation materials. Commonly used inorganic insulation materials are: mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly used for electrical, electrical winding insulation, switch the bottom plate and insulators. Organic insulating materials are: shellac, resin, rubber, cotton yarn, paper, linen, rayon, etc., mostly used to manufacture insulating paint, winding wire unsaturated polyester glass mat sheet and so on. Mixed insulation materials for the above two kinds of materials from the processing of various molding insulation materials, used as electrical appliances of the base, shell and so on.
The role of insulating material is in the electrical equipment to the potential of different charged part of the isolated. Therefore, the insulation material should first have a high insulation resistance and pressure strength, and to avoid leakage, breakdown and other accidents. Second, the heat garolite g7 is better, to avoid long-term overheating and aging deterioration; In addition, there should be good thermal conductivity, resistance to lightning and high mechanical strength and ease of processing and so on.
