Product Description:

1. Introductions:

Mica is a rigid substrate able to withstand very high temperatures and are suited for applications up to 500°F (260°C). Mica heating elements  offer several distinct advantages over other flexible heater technologies, including extremely low leakage, lower material costs, and higher  operating temperatures. Our mica heating element is made by detail order requirments.

2. Applications:
Typical applications of mica heating elements are air heaters, enclosure systems, food service equipment, process and packaging equipment.

Q:What are the commonly used insulating materials?
Mostly used to make insulating varnishes, winding wires, etc. Insulation materials are made of the above two kinds of materials made of various molding insulation materials, used as electrical appliances of the base, shell and so on.
Q:What insulating materials do you need for power tools?
Additional insulation: insulation between the rotor core and the mandrel (insulating plastic powder), between the stator core and the plastic housing shell, is the additional insulation withstand voltage of 2500V;
Q:What type of enameled wire and insulation material is used for the compressor
Enclosed wire and insulation materials for fully enclosed compressors: 1) Refrigerant R12, enameled wire with high strength polyester QZ, insulated with 6400 epoxy resin Insulation H34-4, Polyurethane film for insulating material Green paper (DMD ) Insulation paper; 2) refrigerant R22 and R502, with QF, QXY polyamide imide enameled wire, insulation treatment with EIU epoxy modified impregnated varnish, insulating material with polyimide film and poly Fiber composite foil, F-class insulation DMD insulation paper.
Q:The electrical equipment in the classroom which uses insulating material
Insulation material characteristics: chemical resistance with gloss, some transparent or translucent most of the good insulator light weight and strong processing can be easily mass production, cheap and wide range of uses, utility, easy to color, some high temperature
Q:What insulating materials are used for high frequency transformers?
Where the water is mainly a resin and solvent or resin, oil and solvent composition, is based on polymer polymer, under certain conditions can be cured into an insulating film or insulation of the important insulation material, applied to high-frequency transformers After the surface, the solvent evaporates, the resin or the resin and the oil form a smooth film, showing the original pattern of the object. Easy to dry and durable, and can acid and oil.
Q:The role and definition of insulating materials
According to the national standard GB2900.5 provides the definition of insulating material is: "used to make the device in the electrical insulation of the material." That is, to prevent the current through the material.
Q:Wear-resistant, high temperature, insulation materials which
Epoxy, temperature from 100-400 degrees, processing more convenient. Ceramic is the best and cheap.
Q:What insulating material is best `?
Liquid insulation material, also known as insulating oil. Fill the internal or inter-electrode gap between the solid material to improve its dielectric properties and improve the cooling capacity of the equipment. Liquid insulation material high breakdown strength, dielectric loss tangent (tgσ) small, insulation resistance High specific dielectric constant, in addition, also has excellent physical and chemical properties, such as high gasification temperature, high flash point, low freezing point, thermal conductivity, thermal stability, in the electric field under the suction Small and so on.
Q:What insulating material is used for high voltage cables
Etc., can withstand mechanical force and a certain tension. YJLV32 aluminum core XLPE insulated fine steel wire armored PVC sheathed power cable YJV33 copper core XLPE insulated fine steel wire armored PVC sheathed power cable YJLV33 aluminum core XLPE insulated steel tape armored PVC sheathed power cable
Q:What are the electrical insulation materials
Many types of insulating materials, can be divided into gas, liquid, solid three categories. Commonly used gas insulation materials are air, nitrogen, sulfur hexafluoride and so on. Liquid insulation materials are mainly mineral insulating oil, synthetic insulating oil (silicone oil, dodecyl benzene, polyisobutylene, isopropyl biphenyl, diaryl ethane, etc.) two categories. Solid insulation materials can be divided into organic, inorganic two categories. Organic solid insulation materials include insulating varnishes, insulating glue, insulating paper, insulating fiber products, plastic, rubber, lacquered lacquers and insulating impregnated fiber products, electrical thin films, composite products and adhesive tape, electrical laminates and so on. Inorganic solid insulation materials are mainly mica, glass, ceramics and their products. In contrast, solid insulation material variety, but also the most important. Different electrical equipment requirements for the performance of insulating materials are focused. High-voltage electrical equipment such as high-voltage motors, high-voltage cables and other insulation materials require high breakdown strength and low dielectric loss.
