This Appraisal is for the Copperhead Reinforced Tracer Wire System used for locating underground non-metallic pipelines. This Issue 2 is a replacement for the previous version of the appraisal which had reached its 5-year expiry date.
The system components include:
- (a) copperhead reinforced tracer wire consisting of a high carbon steel wire with a conductive copper cladding and insulated with a high-density polyethylene jacket,
- (b) connectors to join the wire,
- (c) snakePit termination and grounding access points to provide access for direct connection of a transmitter to the tracer wire and
- (d) magnesium grounding rods for installation on tracer wire dead ends to complete the electrical circuit.
The Copperhead system is available with a range of tensile strengths that are designed to suit open cut, horizontal directional drilling and pipe bursting applications.
