The following are some of the noise characteristics and associated countermeasures presented by the motor bearings; here the bearing associates give us a detailed analysis as follows:
1. Foreign matter sound set: After the motor is installed, noise is found when the noise is viewed.
Characteristics: The sound of "啪哩啪哩..." is announced intermittently.
Reason: Foreign matter enters the inside of the bearing.
Countermeasures: Improve the cleanliness of the installation line, rotor and bearings.
2, adhere to the sound of the scene: after the motor is installed; when the noise is seen, there is noise.
Characteristics: The sound of "叽哩叽哩..." is announced consecutively or intermittently.
Reason: The noise caused by the conflict between the adherer and the steel ball.
Countermeasure: Select the stick grease that adheres to the sound of the instrument.
3, the scar sound (friction wear) set: the motor is transported to the air-conditioning plant for noise viewing to find noise.
Features: The sound of "咔啦......" was announced one after another.
Reason: Because of the fluctuation of the oscillation during transportation; the friction between the steel ball and the tumbling of the bearing causes the sound.
Countermeasures: Improve packaging and transportation methods; use anti-friction wear grease; to improve the pass rate.
4, scar sound (Brinell indentation) set: after the motor is installed; when the noise is checked; found noise.
Characteristics: The sound of "咔啦啦......" was announced one after another.
Cause: When the shaft is pressed into the shaft collar or bearing chamber; Brinell indentation is generated inside the bearing.
Countermeasures: Select the bearing depicted by the indentation; to improve the installation qualification rate; "NSK" anti-indentation depiction.

Insulator Hardware

Insulator Hardwares

Insulator hardware for Poleline Hardware refers to the components used to support and insulate electrical conductors on utility poles. Some common insulator hardware used in poleline installations include:

1. Insulators: Insulators are typically made of porcelain, glass, or polymer materials and are used to prevent electrical current from flowing through the pole or other grounded structures. They provide electrical insulation and mechanical support for the conductors.

2. Insulator pins: Insulator pins are used to secure the insulators to the crossarms or other supporting structures. They are usually made of steel or other durable materials and come in various designs to accommodate different types of insulators.

3. Insulator Clevis: Insulator clevis are comprised of multiple insulators connected in series to provide the required electrical insulation for the voltage carried by the conductors. The number and arrangement of insulators in a string depend on the system voltage and other factors.

4. Suspension hardware: Suspension hardware includes various components such as suspension clamps, suspension insulators, and suspension links. These are used to support the weight of the conductors and insulators, ensuring proper tension and alignment.


5. Strain hardware: Strain hardware is used to absorb and distribute the mechanical forces exerted on the conductors due to wind, ice, or other external factors. It includes components such as strain insulators, strain clamps, and dead-end fittings.


6. Crossarm braces: Crossarm braces are used to provide additional support and stability to the crossarms, which hold the insulator strings. They are typically made of steel or other sturdy materials and help to prevent sagging or swaying of the conductors.



Yokelink Insulator Hardware are mainly used in transmission lines. It is used to connect crossarms, thereby joining the crossarms. By joining crossarms together, they are made stronger and more resistant to vibration.They are attached in cross arms of overhead transmission lines for supporting and connecting the crossarms by means other than welding. They join two crossarms or a cross arm with an insulator mounted on it. It is also put into one crossarm for joining cross arms together.
The Insulator cross arm pins have three parts – the crossarm pin base, a crossarm pin body, and the crossarm pinhead. The cross-arm pin base is fitted in an opening of a cross arm.The cross-arm pin body connects the cross arm with another cross arm or a crossarm insulator. The crossarm pinhead is placed on the top end of the cross-arm pin body and holds it into position so that it cannot move outwards.
