SPECIFICTION OF UNIVERSAL DISTRIBUTION CONNECTORS

The wedge type Universal Distribution Connector will consist of locking insert madefrom a special Aluminum alloy of high ductility and electrical conductivity, whichcan be easily removed by screwdriver. When connected, this will provide a tenableelectrical and mechanical connection for solid, stranded or compressed conductorcombinations including AAC, AAC & ACSR. The typical installation procedure ofwedge type connectors has been illustrated at attached Annexure -I A.The dimensions for the wedge shall be manufactured to close tolerances to ensurerepeatability and reliabi!ity ofthc connection.A II sharp edges and burrs shall be removed.The wedges shall be burnished to achieve optimum surface roughness for electricalcontact.

The wedge connector shall meet the current cycle test requirements as per ANSI. C119.4-1998 Class AA. When connected as specifieri. samples shall indicate electricalstability for terminated connectors. The resistance of connection, when measured as

specified shall be stable through out test. The samples shall be tested to 500 on/offcurrent cycles with the control conductor raised between 175 C to 180 C above

. ambient.

The wedge connector shall meet the mechanical requirements as per ANSI C 119.4­1998 Class 3, minimum tension. When tested as specified or 5% of the rated cablestrength of the weaker conductor.The wedge connector shall meet the following thermal shock/salt spray test.a) Hours at 1':>0 C

b) 15 minutes atO C water, immediately from the o\"enc) 30 minutes at 150 C.d) 20.75 hours at worn temperatureSalt spray corrosion. samples shall be subjected to a 30 day salt spray corrosion test.Each daily exposure shall consist of:a) 15 hours in 5% salt spray atmosphereb) 1hour in e drying oven at 100 C.c) 8 hours at room temperature.The supplier also shall supply marine atmospheric enyironmental study on theperformance of their products, minimum 4 years duration.

APPLICATION RANGE

• Can be used up to 120 sq n1m size conductors

• For higher s~zes and high current applicationcartritcige fired connectors ( based on plasticdeforlnation concept) are more suitable.

~N

• Pre!,;ently 15-5561 "Electric PO'MerConnectors"

deals with connectors for current above 200amps and as such only International Standardscan filII the gap.
