TTD Series
Insulated Piercing Connectors
For connecting Insulated Mains to Insulated Mains or Insulated Services.
The Sicame TTD range of insulation piercing connectors (IPCs) provide a fast, convenient and reliable method of connecting overhead low voltage mains to services or other mains. All common types of conductors can be interconnected, including insulated aluminium or copper. The connectors have been tested to IEC and Eurpoean standards, and are approved for use by Australian power distribution utilities (consult for further details).
The Sicame TTD range has a long proven track record in the harsh Australian climatic conditions.
Not suitable for multi-stranded or flexible cables

Not suitable for multi stranded flexible cable or neutral screened cable.
When using 2 bolt connectors, each bolt must be tightened a 1/4 to 1/2 turn alternately, until the shear head operates. For tightening the shear head bolts, use only a 13mm AF, six-sided hexagon socket.
For double insulated cables, the outer sheath should be removed before applying the connector.
