We are Sole Agent for this Product in India.

THE ELIMINATION OF POLLUTION FLASHOVER WITH THE

SYSTEM

INSILCOTE

IF A SUBSTATION IS SUFFERING FROM POLLUTION FLASHOVERS, WHAT ACTION SHOULD BE TAKEN?

• HAND CLEANING?• LIVE SPRAY WASHING?• INSTALL A FIXED WASHING SYSTEM?• SILICONE GREASING?• SILICONE RUBBER COATING?

LET’S EXAMINE THESE OPTIONS…..

HAND CLEANING

LIVESPRAYWASHING

ADVANTAGES:

• NO OUTAGE REQUIRED

DISADVANTAGES:

• NOT SUITED TO ALL CONTAMINANTS• NEEDS SPECIALISED EQUIPMENT• NEEDS SKILLED OPERATOR• NEEDS SOURCE OF LOW COND. WATER• FREQUENCY – NEEDS TO BE DONE OFTEN• INVOLVES RISK OF FLASHOVER FROM INCORRECT TECHNIQUE AND OVERSPRAY• DISTORTION OF FIELDS CAN CAUSE EQUIPMENT FAILURE

FIXEDSPRAYWASHINGSYSTEMS

…AND THE BIGGEST PROBLEM WITH ANYWASHING PROGRAM?….

TIMING!

• CLIMATIC VARIABLES & UNPREDICTABILITY

• MONITORING LIMITATIONS

• PRE-DEPOSITED VS. INSTANTANEOUS POLLUTION

SILICONEGREASING

ADVANTAGES:

• HYDROPHOBIC SURFACE

• CONTAMINANT ENCAPSULATION

• EXTEND MAINTENANCE INTERVAL

DISADVANTAGES:

• HIGH MATERIAL COST

• HIGH LABOUR COST

• LONG OUTAGES

• NOT FOR BULKY CONTAMINANTS

• SPENT MATERIAL DISPOSAL

• UNPLEASANT TASK

WARNING SIGN!

LEAKAGE CURRENTSARE DEGRADING THE GREASE TO A WHITE,WATER-ABSORBENTSILICA.

REPLACEMENT ISURGENTLY NEEDED.

SILICONE RUBBER COATING

GREASE IS NOW BEING LARGELY REPLACEDBY RTV SILICONE RUBBER COATINGS.

INSILCOTE HV2000 COATING FEATURES:

• EXCELLENT HYDROPHOBICITY• THE ABILITY TO TRANSFER THIS WATER- REPELLENCY TO A POLLUTION LAYER ON THE SURFACE• INHIBITS THE FORMATION OF MOIST LAYERS• LIMITS THE FLOW OF LEAKAGE CURRENTS• DUE TO IONISED CONTAMINANTS, IT PREVENTS FORMATION OF DRY BANDS

• INSILCOTE CONTAINS LOW MOLECULAR WEIGHT POLYMERS. THIS IMPARTS WATER REPELLANCY PROPERTIES TO THE POLLUTANTS WHICH GET ACCUMULATED ON THE SURFACE

• INSILCOTE HAS GOOD RESISTANCE TO ULTRA- VIOLATE RAYS AND MANY ORGANIC CHEMICALS

• IT PROVIDES GOOD SURFACE ARC RESISTANCE • USED FOR TRANSMISION LINES, SUBSTATIONS• USED FOR ALL POLLUTED AREAS LIKE CEMENT, CHEMICAL,STEEL, THERMAL POWER PLANTS

MACE TECHNOLOGIES’ INSILCOTE HV2000SILICONE RUBBER COATING HAS SERVEDFOR MORE THAN TWENTY YEARS IN THEMOST EXTREME ENVIRONMENTS.IT HAS BEEN USED IN SUBSTATIONS FROM 11kV TO 400kV AC AND 3kV TO 533kV DC.

INSILCOTE HV2000 IS THE ONLY INSULATOR COATING TO HAVE PASSED ESKOM’SSEVERE APPROVAL PROCEDURE AT THEIRKOEBERG TEST STATION ON THE HARSH WEST COAST OF SOUTH AFRICA
