Tension Clamp For Aluminium Conductor  
                  TECHNICAL SPECIFICATION
1.    SCOPE
      This specification covers the design and construction of Tension of Tension Clamps to be used for the termination of aluminium-conductors at terminal poles and section poles.      
       The Clamps are suitable for used in Tropical zone, with a maximum ambient temperature of approximately 40ºC and a mean annual temperature of approximately 28ºC with high humidity and heavy rainfall.
2.              STANDARD
this specification is make reference to and comply with the requirements of following standard:
BS 3288:1973    -    Insulator and Conductor fitting for
                    Overhead Power Lines
BS 729          -    Hot dip Galvanised
3.              ELECTRICAL SYSTEM
The Clamps will be designed for use on a 3 phase,3 wires, 33/22/11/6.6kv,50 Hz, primary distribution system with the star-point of the source-end transformer earthed through an Earthing Resistor.
4.              DESIGN AND CONSTRUCTION
The Clamps are manufactured from material which is not cause chemical corrosion when in constant contact with aluminium conductor. They are have a tensile strength that the breaking strength that are not less than the breaking strength of the conductors to be connected.
The Clamps are properly designed such that will not cause any unnecessary strain and abrasion on the surface of conductors.
5.              SIZE OF CLAMPS
The Clamps aredesigned to accommodate the following sizes of Aluminium conductors:
a.                  50mm2 Alu. Conductor
b.                  100 - 150mm2 Alu. Conductor
6.              MARKINGS
The Tension Clamps will be indelibly marked as Customer Requirment.
7.              INSPECTION AND TESTS
For evaluation purposes, we will supply the following items to our cusotmer
a.                  A  sample of the Tension Clamp complete with all accessories.
b.   A copy of the test report on tests conducted in accordance to BS 3288 and BS 729
