Insulator Suspension Strings
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.
designs incorporate following three principle features:
High Mechanical reliability and flexibility of
Adequate High Voltage Electrical characteristics.
Fatigue free performance under wind induced vibration
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
