High Voltage Insulation Coatings
Monarch's High Voltage Insulation Coating is especially formulated to
enhance your utility reputation with dependable, cost-effective high voltage
distribution systems. Build the efficient transmission and distribution systems
needed to meet growing global demands for electrical power.
Pollution of outdoor high voltage insulators is a common problem for
utilities, with a considerable impact to power system reliability. A possible outage
in a high voltage system usually corresponds to a severe impact to the power system. In an
effort to prevent possible flashovers due to pollution, high voltage insulation coatings have been
designed, aiming to improve the insulation performance, either by suppressing the formation of surface
conductivity or by increasing the possible insulation level, since the coating can be installed at a time
convenient for the utility and within its operational lifetime is capable of suppressing the pollution
influence at any time.
Monarch's InsulKote high build polysiloxane RTV coating specially designed to give electrical
insulators long-term resistance to water filming and high level of flashover resistance under conditions of
high voltage corona stress, even after extended periods of exposure to ultraviolet light.
High voltage infrastructure can benefit from:
- Superior arcing and !ashover protection
- Reduced leakage currents ensured by long-term hydrophobicity
- Extended maintenance intervals for ceramic, porcelain, or glass insulators
- Lower maintenance and replacement costs
- Minimized equipment problems and failures
- From distribution to very high transmission voltage, to be used over both old &
new insulators (made of glass, ceramic and composites) with excellent dielectric
- Protect against insulation deterioration resulting from particulate contamination
that may occur from dust deposits, salt particles, fog, salinity, high humidity or
other types of contaminants carried in the air.
- The arc resistance of the coating also contributes to protection against glaze
damage of insulators when the coating's water repellant is significantly diminished
and arcing occurs.
- Enhance ability of surface to repel water, resist corona stress, suppression of
leakage current & flash over protection.
- Reduce maintenance works for regular Insulator washing & cleaning, and
replacement of T&D components damaged by flashovers.
- Salt and dust protection on electrical insulators
- Electrical connector insulation
- Corona discharge protection
- Busbar in control panels, on ceramic insulators
- Glass, Porcelain, Composite insulators
- Bushings prevents electrical leakages
- Contaminant caused flash overs
- Arcing caused surface damage
- On poles & cross arms, as Insulating coating in front of control panels as replacement of rubber mats
- On current carrying conductors & similar live parts to avoid accidents
