Professional Porcelain Post Insulators , Bus Post Insulator UNC
Pitch
Description:
TR286 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 | TR286 | 7.6 | 89 | 267 | 1143 | 222 | 3050 | 550 | 610 | 230 |
The HIVOLT station post insulators provide excellent both
mechanical strength and electrical performance for switch and bus
stations ,
which having superior operating characteristics .
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 TR286 insulator are totally 1 single piece . glaze color is
grey .
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 .
TR286 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 .
OEM product are available , we can also change insulator design
based on customer's requirements.
