Aluminium Copper Connectors CAPG type Bimetal Pallel Groove Clamps

 

 
ApplicationFeatures and benefits
For bare overhead aluminium or copper
tap conductors.
Bodies in high strength aluminum
alloy(AIMgSi) or electrolitic copper
Uniformity of material
Long term elasticity
Corrosion withstand
DescriptionPressure padUniform pressure along the clamp
Parallel groove clamps are mainly used
for transmitting current between the
interconnected conductors, for example
for connection loops on terminal poles or
tapping off bus-bars to equipment on
substations. From this function it is
therefore obvious that the electrical
conducting properties and the corrosion
resistance are the main factors for
consideration in the design. Besides this
main area of application parallel groove
clamps are also used for safety loops
and therefore they must provide an
adequate mechanical holding strength.
If conductors made of different materials
are to be connected this can be done by
using bimetallic tubes.
This range of connectors is designed to
connect two paralell conductors in order
to do a derivation of a secondary
conductor, or to close a loop of one
conductor to fit it on an insulator. These
connectors are composed of two parts :
Upper body and lower body, they have
two paralell grooves to receive the
conductor(s).One, two or three bolts are
passing throught the bodies between the
grooves. In aluminium clamps, the two
bodies are made out of high strength
aluminium alloy. In copper clamps, the
bodies are made out of high strength
electrolitic copper. In bimetallic clamps,
the two bodies are made out of high
strength aluminium alloy, and to tight
a copper conductor, one groove is made
with allumiunm alloy and welded by hot
forged bimetallic sheet . The bolts are
made out of hard steel (8.8) and
Dacromatized.
To warranty a reliable tightening,
a pressure pad and a spring washer
are inserted under the bolt head.
Spring washersMaintain the pressure even if a
temperature change causes dilatation
Dacromatized steel bolt 8.8High permanent strength
applied on the clamp
Hot forged compressedbimetalic
sheet (in bimetallic clamps)
Good electrical contact without corrosion
Ridged grooves (forged type only)Improve mechanical pullout strength
and electrical contact
Holding strengthAn adequate mechanical holding
strength is achieved. In case of higher
values two or more PG-clamps should
be used in series.
CoronaGood corona and radio interference
voltage (RIV) behavior due to
rounded shapes.
Corrosion resistanceMaximum corrosion resistance is
achieved by using a clamp material that
matches with that of the conductor,
for example a corrosion-resistant AlMgSi
alloy for conductors made of aluminium,
al-alloy etc.
The requirements will be fulfilled and demonstrated by heat cycle tests.
Overhead Lines
Option
Can be equipped of shearhead bolts.
 
 

 

Description :

 

The aluminium clamp with a friction welded copper insert clearly marked in blue for making copper conductor connections.
The clamps have serrated transverse grooves for maximum conductor contact, use dacromet steel bolts and utilise belleville washers to prevent thermal ratcheting under cyclic loads.Interface between aluminium clamp body and tap copper shape is protected.The clamps are coated with an oxide inhibitor.And hot-dip galvinized steel bolts and nuts was on requirment,also we can change to stainless bolts and nuts with washers.

 

Material:
Body:High strength corrosion resistant aluminium and copper-alloy
Bolts: DIN 933, steel, 8.8, Dacromatized
Nuts: DIN 934, steel, Dacromatized. pressed into lower clamp body
Spring DIN 127, steel, Dacromatized
washers: Dacromatized.

Note:

 

1. Type: F = Forged body; T = Transverse groove
2. that the clamp is provided with corrosionproof stainless steel screws and
hot-dip galvanized steel screws instead of dacromet screws. add suffix "X"
for stainless steel screw. Add suffix "G" for hot dip galvanized steel screws.
