Power Fittings Manufacturers Remind You To Pay Attention To Matters When Purchasing Power Fittings

There are many types of Pre-insulated Sleeve, and their uses are also very different. Different metals have different uses. When purchasing, in addition to paying attention to which one you need, the other thing to pay attention to is the quality of the required power hardware, so as not to waste your money by choosing the wrong one or purchasing inferior power hardware.

The following briefly introduces the classification and functions of several power hardware (respectively, tension clamps, protective hardware, and connecting hardware) so that customers can refer to them when purchasing power hardware.

1. Tension clamp

(1) Bolt-type tension clamp, used to fix the conductor on the insulator string of the tension corner tower, suitable for fixing small and medium-section conductors.

(2) Compression-type tension clamp, one is to fix the conductor on the tension insulator string, suitable for large-section conductors, and the other is to fix the ground wire on the tension pole.

(3) Wedge-type tension clamp, fix the ground wire on the tension pole.

The model of the tension clamp is indicated as follows:

(1) NLD--1, 2, 3... The model means: N-tension clamp; L-bolt type; D-inverted type; such as NLD-1, indicating a type 1 bolt inverted tension clamp.

(2) Indicated by the letter NY. N-tension clamp, Y-crimping type. The number after "-" is the nominal cross-section.

(3) Indicated by the letter NB. N-tension clamp, B-explosion type. The number after "-" is the nominal cross-section.

2. Protective fittings

(1) Anti-vibration hammer. It suppresses the vibration of the conductor and lightning conductor and plays an anti-vibration role.

(2) Pre-twisted wire protection wire. It plays a role in protecting the conductor.

(3) Heavy hammer. It suppresses the excessive swing angle of the suspension insulator string and the pulling up of the conductor and lightning conductor on the straight rod.

(4) Spacer. It fixes the split conductors to be arranged in a geometric shape.

3. Connecting hardware

U-shaped hanging ring, double-joint plate, right-angle hanging plate, extension ring, U-shaped screw, the above hardware is called universal hardware, which is used to connect between insulator string and hardware, between wire clamp and insulator string, and between lightning arrester and pole tower.

Ball head hanging ring, (__qiu tou gua huan _) bowl head hanging plate are special hardware for connecting ball and socket insulators.
