Easy Maintenance Solid Core Post Insulators , Polymer Post Insulator TR288
Description:
TR288 ANSI standard station post insulator has below characters:
| No. | Type | Specified Cantilever Strength KN | Tension Strength KN | Compre-ssion Strength KN | Section Length H, mm | Shed diameter mm | Minimum Nominal Creepage Distance mm | Lightening Impulse Withstand Voltage kV | Critical Impulse Flashover Voltage kV | Low Frequency withstand Voltage Wet kV |
| 1 | TR288 | 6.23 | 89 | 267 | 1372 | 192 | 2950 | 650 | 710 | 275 |
The HIVOLT station post insulators provide the electric power industry with switch and bus insulators ,
which having superior operating characteristics plus high strength for substations.
we are doing our best to provide max. economy and trouble-free service in a wide variety of voltage and strength ratings. our products can be used from 15KV up to 1000kV substations.
the TR288 insulator are totally 1 single piece .
Applications:
HIVOLT station post insulators are well-suited to high voltage and EHV switch and bus construction because
of their strength ,rigidity and adaptability to a wide range of stack heights and BIL ratings .
TR288 are suitable for substations and electrical switch up to 145KV . The insulator can be used as vertical .
Competitive Advantage:
HIVOLT station post insulators are low capacitance insulators, this characteristic enables our product to meet the radio influence voltage requirements required by ANSI C29.9
The sturdy sheds on porcelain column of insulator keep power arc away from the body and protet it from damage . even in the improbable instance that all sheds are stripped off , the arcover distance of the insulator will not be decreased materially .
