Compression Type Dead End Fittings

We can offer compression dead end fittings complete with nuts bolts & jumpers, for all sizes of conductors & earthwires. Dead End Clamps are made of Extruded Aluminium Alloy.

Forged steel dead ends options are available for Link, Eye & Clevis attachments.

Compression type dead ending is most widely accepted practice on EHV lines because of its high Mechanical reliability and Electrical continuity. For distribution line bolted type clamps are popular mainly because of easier installation, without any special tool, maintenance advantage and continuity of jumper. However because of vibration and loosening problems quite often localized heating affects performance and cause outage. Compression type dead end for small diameter conductor has become popular mainly because of its superiority in Electrical conductivity. These are very suitable for AAC, AAAC & ACSR conductor of small diameter. This installation can be done by mechanical crimper having provision for changing dies suitable for hexagonal crimping. While for AAC and AAAC hand mechanical crimper can be used upto a conductor diameter of 16 mm, for ACSR it is not recommended above 14 mm size.

 The compression type Dead end assemblies represent the best technical solution for the High Voltage Transmission Lines both from mechanical and Electrical Point of view for the  following reasons :

 1.      The Dead end assembly has breaking load very close to the rated conductor    strength .  RUL guarantee ultimate strength equivalent to 95% ofthe Breaking strength of the conductor.

2.      The Electrical resistance of the assembly when duly compressed on conductor is less than 75% of the resistance of the equivalent length of conductor.

 3.      The Corona and Radio Interference characteristics are equal or better than       those of the conductors.

 Earthwire dead ends are supplied with attachment fittings 'D' Shackles or Clevis.
