Insulator Tension Strings
To achieve a co-ordinated Electrical and
Mechanical performance to suit system requirement standard Insulator
Hardware Assemblies have been designed. Some of these standard
designs illustrated in this page have been incorporated in the
designs through years of technical research and practical
applications.
The designs incorporate following three
principle features:
1.
High Mechanical reliability and flexibility of movement.
2.
Adequate High Voltage Electrical characteristics.
3. Fatigue free performance under wind
induced vibration condition.
Single conductor assemblies are
principally used upto 220KV.Twin Bundle systems are popular for upto
400KV system. Triple conductor configuration has been used
extensively mainly in 500KV system. Quadruple conductor bundle
system has mainly been used for 750KV lines. However , for lower
system voltage use of bundle conductor is necessary where higher
ampacity is demanded. For example for both 132KV and 220KV , twin
bundle system has been used extensively and for 400KV Quad system
has been used in many countries.
Because of varied nature of terrain and
environment conditions, quite often high mechanical strength rating
and electrical creepage is desired in the string designs. The demand
of various utilities differ even from project to project and as such
there is great necessity of offering suitable designs for specific
requirements. RUL has necessary technical infrastructure to design,
develop and test strings designs for customer satisfaction.
