PRTV outside power equipment insulates with takes shape permanence anti flashover compound coating

PRTV outside power equipment insulates with takes shape permanence anti flashover compound coating,
is a kind of electrical power system uses the new electrical function
material, itâ€™s specially for the electrical network and each round,
loses, uses electricity the customer to be lasting eliminates the
equipment flashover thoroughly the hidden danger then to design, Itâ€™s
developed jointly by the North China electric power academy of science
with our company successfully. The product has the unique chemical
composition and the structure, achieved and surpasses the heat
vulcanization silicon rubber physics electrical specification, Overall
performance and so on more outstanding water repellency nature, as well
as 20 years design service life has provided a kind of new technical
measure for the electric porcelaneous equipment permanence counter-
dirt.

1. Product Execution Qualification

This uses
the North China electric power group company standard "Outside the
Power equipment To insulate with Takes shape the Permanence Anti
flashover the Compound Coating (PRTV) To use Leads Then", With Hebei
silicon valley chemical industry limited company standard Q/HGH
019-2004 â€œOutside PRTV Power equipment Insulates with Takes shape
Permanence Anti flashover Compound Coating" to organize the product the
production and the construction.

2. Range of application

This product
mainly uses in the electrical power system transformer substation and
the transmission line insulator, the power plant and the electric power
user changes outside the electricity equipment as well as other
electrical equipments insulates lastingly anti flashover . After the
porcelain (or glass) the insulator uses this product, Forms the
porcelain (or glass) the skeleton complex effect, Enhances one kind of
standardized disposition plan which outside the power transformer
equipment insulates. Is suitable in alternating and direct circuit
system rated voltage 1~750kV, Environment Temperature -50℃~ +50℃, Under
the contamination condition moves outside the transformer substation
and the impractical transmission line equipment insulates antifouling,
Prevention flashover, Enhances the equipment outside to insulate the
rank.

3. Operation Guide

To porcelain
(or glass) insulator superficial thorough clear dirt, Removes the
contamination, the fat and other attachments, After waits the electric
porcelaneous surface pure to be dry, May use to spurt spreads or
brushes spreads and so on to spread spreads the method to carry on the
construction, Coating thickness is 0.5 ~ 0.6mm, the coating should leak
proof spread, not dribble, does not hang the silk, The surface is
smooth, levels also does not have the air bubble. Originally has used
the RTV equipment, Should be clean the unreliable attachment cleaning
up, remove the contamination, After uses the special-purpose processing
medicinal preparation to clean, Again executes spreads PRTV.

4. Package 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 when the
coating uncaps the use, if has not used up, Should cover securely
immediately the airtight preservation.
