RTV Insulator Anti Flashover coating

The
electrical power system Anti Flashover the coating with the single
component normal temperature solidification silicon rubber is the RTV
insulator Anti Flashover the coating is our company in domestic first
develops in 1990 the beginning of ages successfully. The silicon valley
brand sign RTV insulator anti flashover the coating to pass, the
provincial level appraisal, The nation anti Flashover the expert group
to appraise,ISO9001 International quality system authentication and
sign DL/T 627 complete patterns experiments; its performance index has
achieved the international advanced level . In metallurgy, cement,
chemical industry, mine and salt mist and so on, each kind of
contamination environment application, and in 500kV system big area
use, displays finely anti flashover performance, since has drifted net
moves for ten years, does not have dirt to flashover accident, has
guaranteed the electrical network movement security and is reliable.

1. The characteristic and the performance

Â· The fine hydrophobic character and fast, is balanced the hydrophobic migratory nature which, continues;

Â·
The anti-flashover the voltage to be high, The anti- electric arc,
bears leaks the mark, the electrical insulating property is fine;

Â·
The high module, high strength, excels in the adhesion, High corrosion
tolerance, Satisfied condition overhaul request;

Â·
Bears the ozone, bears the ultraviolet ray, bears the environment
aging, Does not get up the skin, Does not crack, The effective running
time is long;

Â·
Single component normal temperature solidification, In -20 ℃ still
might construct, Easy to operate, In the normal maintenance time
exempts sweeps clear, The efficiency is high.

2. Main qualification

This equates
use department sign DL/T627 "electrical power system Anti flashover
Coating with Normal temperature Solidification Silica gel", And has
drawn up higher enterprise standard QB/SV09 "The RTV Insulator Anti
flashover Coating" and QB/SV08 "RTV Coating Construct control Standard"
comes the standard product the production and the construction
application.

3 .Range of application

This is
suitable for rated voltage 0~750kV,Ambient temperature -50 ℃ ~200
℃,Under the contamination condition moves junction, direct current
system, Mainly uses in the power supply bureau transformer substation,
the power plant booster station and loses the distribution line
insulator and the chemical industry, the steel and iron, the electric
railway, the mine pit and all easy contamination, the easy mist, to
pour water on the moist electrical equipment, Enhances the equipment
outside to insulate the rank, prevents the flashover accident the
occurrence.

4. Operation Guide

Before the
construction carries on the convention to the porcelain insulator or
the glass surface to sweep clear, Decontamination and degreasing, fat
processing, The maintenance surface clean is clean. May use to spurt
spreads or brushes spreads the way to carry on the construction,
Coating thickness should regard the scene contamination degree but to
decide, Thickness 0.3 ~ 0.5mm, The coating should leak proof spread,
not dribble, does not hang the silk. . When the coating uncaps the use,
If has not used up, Should cover securely immediately, The airtight
preservation next time again will use.

5 .Packages and Storage

This product
packing in airtight metal container, when storing and transportation
should maintain dry and ventilates, Prevented all day exposes to the
sun, the rain drenches. The storage time is 1 year, Duplicate surpassed
the storage time after to examine qualified still may use.
