The system for pulling wire through a conduit includes a cable puller and a remote controller. The cable puller may pull a wire through a conduit. The wire may be removably coupled to a cable coupler located on the rear of the cable puller. The cable puller may be inserted into a first end of the conduit and may progress to a second end of the conduit under the influence of a plurality of tractors. A camera that is mounted on a faceplate at the front of a housing of the cable puller may transmit one or more images to the remote controller. One or more visible light sources and one or more infrared light sources may provide illumination for the camera. Movements of the cable puller may be controlled remotely using the remote controller.

A wire holder device is disclosed. The wire holder device may have four main faces and one wire channel running across the main face. Wire holder members may have four wire channel sections, which may have different volumes, that may be a slot for holding a wire. Between the wire holder members may be an unframed base section, which may provide a platform for a wire tie.

A cable includes: a cable main body; a first adhesive layer in contact with an outer peripheral surface of the cable main body; a protective member that covers an end part of the cable main body; an outer peripheral member that covers a part of the protective member; and a second adhesive layer on an inner peripheral surface of the outer peripheral member and in contact with the protective member. Adhesive strength of the second adhesive layer is larger than adhesive strength of the first adhesive layer.

This invention relates to an improved component (10) for replacing pipes, in particular underground pipes. The invention also relates to a trenchless method of removing pipes using the improved component, and a kit of parts for use in removing pipes. The improved component (10) is securable to a cable (14) and has a body (30) with a recess (26) to accommodate the end (18) of the pipe (12) in use, the recess being surrounded by a collar (24). The improved component is a two-part component, the first part (20) being securable to the cable (14) and the second part (22) including the body, the two parts being made of different materials. There is also provided a kit of parts including cooperating alignment elements of standard dimensions, and a method of removing an underground pipe.

There is provided a male cable connector (1) for reversibly connecting a computer network cable (7) to form at least one electrical connection or one optical connection to a second component, said male cable connector (1) comprising a male member (3) enclosing at least one electrical lead (14) electrically connected to one electric contact surface (13) and the network cable (7) or said male member (3) enclosing at least one optical fiber (17) connected to an optical connection surface (22) and the network cable (7), said male member (3) being associated with a front direction which is parallel to the longitudinal axis of the male member (3) and directed from the cable (7) towards a forward end (11) of the male member (3) characterized in that said at least one electrical contact surface (13) or at least one optical connection surface (22) is arranged on the surface of the male member (3) and the male member (3) has a bore (4) for connecting a pull-cord. There is also provided a female connector, adaptors, cables and kits.

A system and method include a gauge device and one or more of a communication device or a pulling assembly. The gauge device may be configured to send a message to display on one or more of the communication device or pulling assembly. Additionally or alternatively, the gauge device may be configured to send the message to be processed by pulling assembly to determine and perform a pull action. Additionally or alternatively, the gauge device may be configured to send the message to be executed by the pulling assembly to perform a pull action.

Method for installing a cable comprising: a first phase with at least the steps of: introducing the cable into a first duct, attaching at least a first pig to the cable, introducing a liquid at first pressure and first flow into the first duct, stopping the cable when, or after, its foremost end has reached an exit of the first duct, a second phase with at least the steps of: attaching at least a second pig to the cable, introducing again a liquid at first pressure and first flow into the first duct, introducing the liquid at second pressure and second flow, compensating, at a location between the first duct and second duct, for a difference in flow or volume of liquid.

The present disclosure relates to a method for festooning a power cable while deploying it in a deployment site comprising a rail having a start and an end, the method comprising the steps of: providing the cable with a plurality of cable holders slidably movable along the rail, each two consecutive holders being spaced at a holder predetermined distance on the cable; providing a festooning apparatus after the start of the rail, the festooning apparatus comprising a lowering device movable between a raised position and a lowered position; deploying the cable along the rail by repeating the following sub-steps: engaging on the rail one holder after the other and moving them thereon; when one holder oversteps the festooning apparatus, operating the festooning apparatus to move the lowering device from the raised position towards the lowered position, thus engaging the cable at a point between two consecutive holders; when the lowering device reaches the lowered position, obtaining a sagged portion of cable and a shortening of the holder predetermined distance; operating the festooning apparatus to move the lowering device from the lowered position towards the raised position, thus disengaging it from the cable; fixing the shortened holder predetermined distance between two consecutive holders at each side of the sagged cable portion; and advancing the sagged cable portion along the rail.
