Proper treatment and maintenance of the equipment will help to maintain the protective capacity of the products.
Tools should be kept clean and dry and protected from damage during use, transportation and storage. Tools should be handled with care and stored well protected from moisture. Equipment should be thoroughly inspected before each use.
Earthing equipment should be regularly checked in accordance with the following points to ensure safe and reliable use of the tools. If the cable insulation is damaged or if the inner conductor is exposed, this should be considered a serious fault and scrapping should be considered.
A more comprehensive inspection, so-called. “Periodic inspection” shall be carried out by an approved inspector and should be carried out once a year, possibly at shorter intervals for equipment subject to heavy wear, see “Services”.
CAUTION: Devices subjected to short-circuit current shall be scrapped unless proper investigation, calculation and examination have shown that the effect has been so moderate that it has not produced any adverse mechanical or thermal effects. If there is any doubt that the device is not fault-free, the device shall be scrapped.
1. corrosion damage
Check for corrosion damage on the contact surfaces of the conductor clamp/earth clamp. If damage has occurred, the contact surfaces must be cleaned. In the event of severe corrosion damage, the clamp must be discarded and replaced with a new one. Ensure that the spindle thread runs easily all the way.
2. cable lug connection
Check the connection of the cable lug to the clamp – the screw must be tight and the cable lug well anchored. Check for breakage on the cable lug.
Twisted (not broken) cable lugs can be adjusted to the correct position. Then check for breakage and tightening torque. If the screw must be tightened, the spring washer must also be replaced as it has lost some of its locking ability.
3. damaged rope attachment
The most common damage to an earthing device is at the rope attachment. Check that no wires are damaged. In the event of wire breakage, the attachment must be re-pressed. If the wires are intact, insulation damage can be temporarily repaired with e.g. vulcanized tape, adhesive tape, etc.
4. Damaged wire rope
Check for damage to the wire rope. If the wire breaks, replace the rope with a new one. Insulation damage is repaired temporarily with e.g. vulcanized tape, adhesive tape etc.
5. Dirty rod
Control and earthing rods must be dry and clean. A dirty rod is cleaned with acetone or alcohol. This is done in a ventilated area. The rod must then be treated with silicone. Suitable silicone fluid is DC 200 100 cSt applied with a cloth.
6. Damaged bar
Check that there are no impact marks on the bar. If there are severe impact marks, the bar should be discarded.
7. Damaged splice fittings
Check that there is no damage to the splice fittings. Damaged fittings are replaced with new ones.
8. Damaged grip stop
Check that there is no damage to the grip stop and marking. If the grip stop is damaged or the marking is missing, this must be repaired.
