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.

 

3. Main features of Mica Parts:

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.

Q:What are the commonly used insulating materials?
Commonly used inorganic insulation materials are: mica, asbestos, marble, porcelain, glass, sulfur and so on, which can be divided into inorganic insulating materials, organic insulating materials and mixed insulating materials.
Q:What type of enameled wire and insulation material is used for the compressor
Closed compressor, or semi-enclosed compressor, motor stator coil, and refrigerant, frozen oil have direct contact, refrigerant, frozen oil will not damage the insulation of the coil, enameled wire insulation material problems The Small to the refrigerator, freezer compressor, air conditioning compressor, large to semi-closed, fully enclosed chillers, are related to the coil insulation material. To tell the truth I only demolished medium-sized compressors (semi-enclosed compressors for cold storage). Large semi-enclosed high-pressure refrigeration compressor (6KV, 10KV) I only seen in the manufacturer, did not break
Q:What is the 8 ° C rule for insulating materials?
Such as A-class insulation material limit working temperature of 105 ℃, when the ultimate operating temperature of 8 ℃, its life will be reduced by about half, which is 8 ℃ thermal deterioration rules.
Q:What is the thermal aging and electrical aging of insulating materials?
Electrical aging more common in high-voltage electrical appliances, the main mechanism is the occurrence of partial discharge of insulating material under high pressure, resulting in strong oxidant ozone. Ozone is easy to cause ozone cracking of the material. Partial discharge will produce nitrogen oxides, which combine with the moisture to produce nitric acid, corrosion of insulating materials; partial discharge of high-speed charged particles bombardment of insulating material molecules, will promote its ionization, fission and damage; in addition to local discharge will make dielectric loss Increased, local heat of the material, resulting in heat aging.
Q:What is the electrical performance of insulating materials
The electrical insulating material is a material that is electrically insulated from the device and has a certain mechanical strength, typically having a resistivity of 106 to 1019.cm. Their function in electrical technology is as follows: 1 Insulate the conductor from the other parts; 2 Separate the conductors of different potentials 3 Provide the conditions for the energy storage of the capacitor 4 Improve the potential gradient in the high voltage electric field.
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
Alumina - high temperature, corrosion resistance, wear resistance. Good electrical insulation 1600 ℃. For crucible, high temperature thermocouple casing, knives, mold and so on. Silicon nitride - has good high temperature strength, thermal expansion coefficient is small, high thermal conductivity, thermal shock resistance, the use of temperature as alumina, good electrical insulation. 1200 ℃ still have a high hardness. For mechanical seal ring, thermocouple casing, steam turbine blades and so on. Silicon carbide - high temperature strength, 1400 ℃ when the bending strength of (500 ~ 600) MPa. For the nozzle, furnace tubes, high temperature bearings, high temperature heat exchangers 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 is the insulating material in the middle of the connecting wire?
The original wire is insulated paint, you often use, you can also use quick-drying insulating paint.
Q:What is the DMD insulation material?
DMD insulating paper, the product is a layer of polyester film coated with adhesive, one side for the polyester fiber non-woven composite, calendering from a composite insulation products, referred to as DMD.
