NKI are composite tension/suspension insulators with silicone housing. They are designed for
installation on overhead power lines with rated voltages up to 52 kV.
Characteristics
NKI composite tension/suspension insulators offer the following features:
• UV radiation and chemical resistance,
• weathering and aging resistance,
• silicone rubber housing without additives,
• suitable for aggressive and polluted environments (industry, seaside, desert climate, etc.),
• impact insensitivity.
Installation
The installation of composite tension/suspension insulators NKI follows directives and technical
regulations. They are typically installed in new constructions, reconstructions, and during
maintenance. It is important to note that the installation of NKI insulators, regardless of the
previously installed insulators, does not affect the insulation coordination in power system.
