NKI are tension/suspension composite insulators coated
with silicone rubber. They are designed to be installed in
overhead power lines with voltage up to 52 kV.
Tension/suspension composite insulators NKI are:
• resistant to UV radiation and chemical influences,
• resistant to weathering and aging,
• coated with silicone without additives,
• suitable for aggressive environments (industry,
seaside and desert climate,…),
• insensitive to impacts.
The position for installing tension composite insulators NKI
is decided by directives and technical regulations. They
are being installed in new constructions, reconstructions
and at maintenance. Newly installed NKI insulators have no
impact on any change of insulation coordination regardless
to previous installed insulators in overhead power lines.
