154 kV Busbar Grounding Equipment

PROMOTION

It was built to ensure the life safety of employees by grounding the lines during the maintenance and repair period of medium and high voltage lines.

USE

The equipment can only be used by authorized personnel following the written instructions. Do not approach the grounding cable while manoeuvring.

1. First, the busbar clips and grounding clamps will be screwed to the cables with the bolts and spring washers on them and tightened with the key in the bag so that the spring washers will not come loose,

2. Earth clamps will be tightly clamped in a metal area to ensure grounding.

3. Busbar clips will be attached to stankas

4. After making sure that the earth clamp is firmly attached, the busbar clips will be attached with the help of the stanka.

5. While the equipment is being dismantled, first the clips will be removed from the busbar and then the ground vise will be opened.

EQUIPMENT PARTS

1. 3 Pieces of Aluminum Line Clips to grip lines from 474MCM to 954MCM and attach to the line by screwing

2. Copper braided insulated cables with a cross section of 70mm2, combining the grounding clamp in 3 clips

3. Earth clamp made of aluminum, tightened with a thumbscrew, which provides the connection of 3 cables to the section to be grounded.

4. Ø 40mm diameter glass fiber reinforced synthetic resin tubular grounding sticks used for attaching and removing 3 pieces of grounding clips from the line

5. Electrostatic painted, locked metal bag containing 1 piece of clips and vices

TANKS TO BE USED

For 2 pieces of 154kV lines, 2m long, all of them 4m long, with nuts at the end

DEFINITION

154T stanka is made to be used in high voltage busbars and distribution centers for grounding lines and busbars.

STRUCTURE

- 154T stanka is tubular made of Ø 40mm glass fiber reinforced synthetic resin. It is made of 2 pieces of 2m length, which are used by being attached to each other. Its total length is 4m.

- It should not be used at a higher voltage than the usage voltage written on the sticks.

- The test voltages of the stankas are not less than the following values.

- Its mechanical strength meets TEAŞ bending conditions.

- There is a disc on the stankas that limits the holding area. The metal parts on it are of stainless type.

- The structure of the stankas is in the form of a tube, and it is closed from two heads to prevent moisture.

- The 3 parts of the stanka should not be used without being attached to each other.
