CABLE INSTALLATION

摘要

A method for use in connection with installing a cable into a conduit having a first end and a second end, to confirm whether air introduced into the conduit at the first end is flowing out of the conduit from the second end, the method including the steps of: substantially blocking the second end, so that when the air is introduced into the conduit its flow from the second end will be impeded; introducing a flow of air into the first end; and detecting a change in a property of the air within the conduit whereby it can be confirmed if the air is flowing to the second end.
