G&W PSC (Preformed
Stress Control) terminations meet all industry requirements
and is a Class 1 (outdoor) termination as defined in IEEE
48 standard for high voltage terminations. It contains a porcelain
insulator and factory made elastomer stress relief for use
on all synthetic solid dielectric cables. Sizes are available
for all shielded cables in voltage classes from 2kV through
46kV and conductor sizes through 2000 KCM.
Product
Features:
- The porcelain insulator has maximum
resistance to moisture, industrial pollution and seacoast
pollution. Porcelain is the most reliable insulator
for use where insulator dryband arcing may occur.
- The brass top cap has maximum resistance
to industrial and seacoast pollution.
- O-rings seal the top cap to the
porcelain. This is the most reliable and proven seal
available in the industry.
- Connectors are available for aluminum
and copper conductor cables.
- The external connection to the
overhead system may be made with a eyebolt,
aerial or spade termination connector.
- All the aluminum lower castings
are Almag 35, the most corrosion resistant aluminum
alloy available.
- The termination lower casting makes
the cable shield ground connection with no extra parts,
straps or soldering.
- The electric stress control cone
is a factory made soft elastomer which also seals
the cable shield to environmental moisture.
- The G&W spring-loaded elastomer
filler is the most reliable factory made dielectric
system available. The resulting dielectric interfaces
have high dielectric strength, prevent ingress of
moisture and accommodates the thermal expansion and
contraction of the cable.
- The G&W spring loaded elastomer
system is the most reliable method to provide continuous
mechanical force to the elastomer, thereby compensating
for elastomer permanent set.
