23.14 Maintenance of electrical contacts
To prolong the lifetime of electrical contact surfaces and to provide
proper electrical connection under all conditions and to maintain a high
availability of the WECS system.
The maintenance is carried out by applying contact lubricants to electri-
cal contact surfaces. For best result the contact surface should be cleaned
with aerosol electrical contact cleaner before applying the lubricant.
Contact lubricants are specially formulated greases and oils that
reduce friction and enhance the electrical performance of current
carrying metal interfaces in switches and connectors. They also exhibit
a neutral pH thereby avoiding surface corrosion.
Note! Prior to use read the product information.
Warning! To avoid shock or possible fire, disconnect power to any system
before applying conductive lubricant. Insure positive and negative
contacts remain isolated. Improper use can result in shorting, arc-
ing, or shock.
Wärtsilä recommends to regulary every 2000 - 4000 running hours or
every 6 month maintain the electrical connector contact surfaces with
contact lubricant. The contact treatment greases listed below can be
ordered from Wärtsilä.
The recommended chemicals are:
Electrolube SGB20S 20 ml Syringe, part No. 387 022.
This paste is recommend to be used on the contact surfaces of
main electronics connectors and sensor connectors.
Same active substance as SGB200D but in different consistence,
i.e. paste instead of aerosol.
Electrolube SGB200D 200 ml Aerosol (Flammable),
part No. 387 021.
This spray is recommended to be used on contact surfaces of
main electronic (SMU, DCU, RM, MCU and oil mist detector)
connectors. Since it is an aerosol there are special requirements
of transport handling.
Chemtronics CW7100 6.5 g Syringe, part No. 387 023.
This is a heavy duty paste. The electrical conductivity is very high
due to the 100 % silver filled grease, see caution below. Should be used
on problem sensor and power contact surfaces where SGB grease is
not sufficient.
Caution! Care should be taken since this chemical is very conductive and will
cause short-circuit/earth fault if wrongly applied. Must be placed directly
on the contact surface and in very small amounts.
