380 kv Line 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 line 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. Line clips will be attached to stankas

4. After making sure that the ground vise is firmly attached, the line clips will be attached to the line with the help of the stanka.

5. While the equipment is being dismantled, first the clips will be removed from the lines and then the earth clamp will be opened.

EQUIPMENT PARTS

1. 3 Pieces of Aluminum Line Clips to grip lines from 954MCM to 1272MCM 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 3 pieces of 380kV lines, 2m long, all of them 6m long, with nuts at the end

DEFINITION

380T stanka is made to be used in grounding equipment of lines and busbars in high voltage line and distribution centers.

STRUCTURE

- 380T stanka is tubular made of Ø 40mm glass fiber reinforced synthetic resin. It is made of 3 pieces of 2m length, which are used by adding to each other. Its total length is 6m.

- It should not be used at a voltage higher than the usage voltage written on the sticks. - The test voltages of the sticks are not less than the values below.

- 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.

I. Warning Sign: Test 500kV use 380kV hands will not go beyond here 380T

II. Warning Sign: First, firmly clamp the earth clamp, then attach the clips to the lines and busbars with the help of stanka.

- When disassembling the equipment, first remove the clips from the line and busbar with the stanka, then open the ground vise.

- Do not approach the ground wire during the maneuver.
