Dear sir,
Greetings 

We are facing frequent trippings (outages) on many of 110 kv overhead transmission lines due to less creepage distance of long rod/cap and pin insulators. 

We will appreciate, if you suggest some solution like your product *Creepage extender* or something better than this.

Your response will be highly appreciated. 

Thanks and best regard

Engr. Muhammad Abdohoo
