[knowledge] Several commonly used high-temperature insulation material grade
Xiao Bian wants to introduce the grades of high-temperature insulation materials for everyone. I hope everyone can learn more about the relevant aspects.
Insulating materials commonly used by electricians are classified into inorganic insulating materials, organic insulating materials and mixed insulating materials according to their chemical properties. Commonly used inorganic insulating materials are: mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly used as windings for motors, electrical appliances, switches, and insulators. Organic insulating materials include: shellac, resin, rubber, cotton yarn, paper, hemp, rayon, etc. Most of them are used to make insulating paints, covered insulation of winding wires, etc. The mixed insulating material is a variety of molded insulating materials made of the above two kinds of materials and used as a base and a shell of an electrical appliance.
The function of the high-temperature insulation material is to isolate the live parts with different potentials in the electrical equipment. Therefore, the insulation material should first have a high insulation resistance and compressive strength, and can avoid accidents such as electric leakage and breakdown. Secondly, the heat-resisting performance is better, and aging and deterioration are avoided due to long-term overheating; in addition, good thermal conductivity, moisture resistance, lightning resistance, high mechanical strength, and convenient process processing are also required. According to the above requirements, the performance indexes of commonly used insulating materials include dielectric strength, tensile strength, specific gravity, and expansion coefficient.
The compressive strength of high-temperature insulation materials: The higher the voltage applied across the insulator, the greater the electric field force in the charge of the material, and the more likely the ionization collision occurs, causing the insulator to break down. The lowest voltage at which the insulator breaks down is called the breakdown voltage of this insulator. When a 1-mm-thick insulating material is broken down, the voltage kV to be applied is called the dielectric strength of the insulating material, which is simply referred to as the dielectric strength. As insulation materials have a certain degree of insulation strength, various electrical equipment, various safety equipment (electrician's pliers, electroscope, insulating gloves, insulating rods, etc.), various electrical materials, manufacturers are required to provide a certain allowable voltage, said Rated voltage. The voltage applied during use must not exceed its rated voltage to avoid accidents.
Tensile strength of high-temperature insulation materials: The tensile force per unit cross-sectional area of ​​the insulation material can withstand, for example, the glass can withstand a tensile force of 1400 Newton per square centimeter.
The insulation performance of high-temperature insulation materials is closely related to temperature. The higher the temperature, the poorer the insulating properties of the insulating material. In order to ensure the insulation strength, each insulation material has a proper maximum allowable working temperature below which it can be used safely for a long period of time, and if it exceeds this temperature, it will rapidly age. According to the degree of heat resistance, the insulation material is classified into Y, A, E, B, F, H, and C grades. For example, the maximum allowable operating temperature of Class A insulation materials is 105°C. Most of the insulation materials used in distribution transformers and motors are Class A.
The mechanical transmission device in the reciprocating movement of the more, will lead to very large abrasion of random cable. Nylon drag chain (Nylon Cable Drag Chain) is one of the most important in the facilities in the operation of the complete protection to the cable, and can supply after mechanical traction.
Nylon Drag Chain (Nylon Cable Drag Chain), has the high pressure and tensile load, good toughness and high elasticity and abrasion resistance, flame retardant, high and low temperature performance is stable, can be used in outdoor. The use of nylon content decided to Drag Chain strength and wear resistance as well as the running noise size.
Nylon drag chains (Nylon cable drag chain) are resistance to oil, salt, and have certain ability of acid and alkali resistance.
Nylon drag chain (Nylon cable drag chain) inspection method:
1. Make the nylon drag chain (Nylon cable drag chain) against the sun, If you can see the reflected light even without astigmatism, then the drag chain materials evenly, the quality is good.
2. Touch each edges and the surface of nylon drag chain (Nylon cable drag chain), if you don't prick the hand and feeling smooth, you can determine the production with minimal error range of mould.
3. Rub the surface of the nylon drag chain (Nylon cable drag chain) with wood, if the drag chain surface soon appeared pits, and there are the shape of clastic makings falls off, we can judge the raw material of nylon drag chain (Nylon cable drag chain) with poor quality. If you feel very difficult when rub drag chain, pits appeared and falling debris in short filaments, we can determine the raw materials of the nylon drag chain (nylon cable drag chain) joined the high strength material such as glass fiber, which make its wear resistance is higher.
Raw materials are fundamental in determining the quality of engineering plastic drag chain ((plastic cable drag chain)), so the quality of raw materials is a key point. At the time of manufacture, we choose the original package materials as raw materials and can`t add recycling of used materials. This will increase the drag chain itself toughness, reduce the damage caused by low temperature, and reduce the emergence of the problem.
