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.
