Frequently Asked Questions

What is the difference between the "C" and "CN" designations?
The primary difference lies in the suspending modes. Models with the "C" designation are typically used for suspension, while "CN" models are designed for tension applications.
What is the maximum mechanical failing load available?
In this product range, the mechanical failing load ranges from 70kN for the U70 series up to 120kN for the U120 series.
What is the standard creepage distance for these insulators?
All models listed in the parameters table feature a nominal creepage distance (L) of 220mm.
What type of socket coupling is used?
These insulators use a standard 16C socket coupling, ensuring compatibility with standard power line hardware.
How do these insulators perform under arc current?
The insulators are tested for electrode performance withstanding a power frequency current of 10kA for a duration of 0.2 seconds.
What is the nominal weight of each unit?
The weight for these units is consistently approximately 4.5kg per piece, making them manageable for installation while maintaining high strength.
