Product Description:

1. Introductions:

Mica tube is made of mica paper with highperformance organic silicon resin. After heating and pressing, the mica plate can be made into rigid or flexible insulating plates. The mica content is about 90% and the organic silicon resin content is 10%. 

 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 tubes are featured with high strength, good performance, less smoke, less odor etc. This series mica plates are used mainly in household appliances (toaster ovens, microwave ovens, warm air blowers, hair dryers, electric iron etc.), metallurgy (such as linefrequency furnaces, medium frequency furnaces, electric arc furnace, etc.), medical equipment and other industries, used as the heating support, lining plate and partition plate of the electric appliances described above.

Q:What insulating materials do you need for power tools?
Reinforced insulation: the voltage between the live parts and the accessible housing is 3750V, such as the voltage between the brush and the cover surface; double insulation: basic insulation + additional insulation. Main insulating material: green paper or DMD Insulation paper for basic insulation; shaft insulation and plastic housing for additional insulation; rotor insulation end plate, stator insulation end plate, used to control the creepage distance and electrical clearance; brush grip bakelite powder, used to strengthen the insulation; other parts (Power plugs, commutators, switches, etc.) These are pressure requirements.
Q:What insulating material is used for high voltage cables
High - pressure rubber sheathed flexible cable UGF: Model and name: UGF - 6000V mine rubber flexible cable UG - 6000V mine rubber flexible cable. Implementation of the standard: TL / J30-94. UGF cable Uses: AC rated voltage 6kv and below mobile power distribution equipment and mining machinery; lifting transport machinery.
Q:Wear-resistant, high temperature, insulation materials which
Hexagonal boron nitride - good heat resistance, thermal stability, thermal conductivity, hardness is not high, the only easy machining of ceramics. Is the ideal heat dissipation material and high temperature insulation material. For high temperature containers, semiconductor thermal insulation materials, high temperature bearings, thermocouple casing. Cubic boron nitride - hardness close to the diamond, excellent wear-resistant materials. For high-speed cutting tools, such as drawing die.
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 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 kind of insulation is the insulating layer of the aluminum plate?
Ordinary heat conduction is made with fiberglass PP2. High thermal conductivity materials are made of thermally conductive
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 insulating materials are used for high frequency transformers?
Which is divided into solvent and solvent-free paint is divided into two major categories, mainly used for dipping motor, electrical coil and insulation parts to fill its gap and microporous, immersion paint can be cured in the surface of the formation of continuous formation Of the film, and the coil into a solid as a whole, in order to improve the insulation structure of the moisture, thermal conductivity, dielectric strength and mechanical strength of the performance.
Q:What is the DMD insulation material?
DMD (Dacron / Mylar / Dacron) full name polyester film polyester fiber non-woven soft composite foil, is a two-layer polyester non-woven fabric in the middle of a layer of insulated polyester film composite made of three insulation materials.
Q:What insulating materials are used for transformers
Dry type transformers before the 1960s are mainly B-type insulation of the open-type dry-type transformers, product model for the SG type. When there is no foil coil, the low pressure for the majority of multi-root and around the layer or spiral coil, high pressure for the pie coil. Wire for the double glass envelope or single glass fiber package enamel enameled wire. The rest of the insulating material is mostly phenolic glass fiber materials. The impregnation process for the room temperature, atmospheric pressure with B-class insulation impregnated paint were high and low pressure coil impregnation and drying at the temperature (drying temperature does not exceed 130 ℃). Although this dry-type transformers than oil-immersed transformers in the fire performance has made great progress, but its moisture, anti-pollution performance is worrying. Is no longer produced. Nevertheless, its successful electrical, magnetic, thermal calculations and structural design have laid a good foundation for the new H-class insulated open-ended transformers that have evolved later.
