Abstract: The present invention relates to a reusable mains-power electrical connector. The connector includes a connector body for receiving cables and fasteners. One or more protectors are located within the body to protect the received cables when the fasteners engage with the protectors to fasten the cables within the body. The connector also includes relieving means for relieving the cables of the protectors when releasing the fasteners to remove the cables. Advantageously, the connector may be re-used when the fasteners engage with the protectors to fasten new cables received within the body.

Abstract: The present invention relates to a monitoring system of wind-induced motion or vibration in at least one overhead cable (102), in particular a conductor aerial cable (102) of a transmission or distribution electric line. The monitoring system comprises: at least three sensor nodes (104) adapted to be installed in positions different from each other on a first overhead cable (102) and configured for detecting the motion or vibration through a synchronous signal acquisition. Each of the at least three sensor nodes (104) comprises a respective triaxial accelerometer sensor (301) configured for acquiring a first node signal and a first processor (302) configured for identifying, in the first node signal, a maximum node amplitude and an associated node frequency through a spectral analysis of the first node signal.

Abstract: The present invention relates to a power line coupler for coupling a pair of cables together. The coupler includes at least one protector for protecting the cables. A clamp is provided for clamping the protector and cables together.

Abstract: The present invention relates to a power line coupler for coupling a pair of cables together. The coupler includes a protector for receiving and protecting the cables. The protector includes a pair of protection members between which the cables can be received. A clamp is provided for clamping the protector and cables together.

Abstract: The present invention relates to a power line coupler for coupling a pair of cables together. The coupler comprises a protector for receiving and protecting the cables. A clamp is provided for clamping the protector and cables together. In many embodiments, the protector comprises an inner tube in which the cables can be inserted from opposite sides. In one embodiment, the clamp comprises an outer tube in which the protector is located.

Abstract: The present invention relates to a mains-power electrical connector. The connector includes a core defining passages for receiving respective cables, and apertures for receiving fasteners to fasten the cables within the passages. Windows terminate the passages. A light penetrable cover is provided for covering the core and the windows. The fasteners may be in the form of shear bolts.

Abstract: A screw clamping apparatus includes a shank and a drive member for exerting a driving force on a shank to screw the same into a bore to exert a clamping force on an article. The shank is provided to shear once a predetermined turning torque from the drive member, and hence clamping force, is achieved and the plane of shear can be accurately determined relative to the surface of the article on which the bore is formed and into which the shank is screwed. This is an advantage over the conventional clamping screw, which is provided to shear at one fixed weakened location and, when sheared, can leave an undesirable protrusion.

Abstract: A screw clamping apparatus includes a shank and a drive member for exerting a driving force on a shank to screw the same into a bore to exert a clamping force on an article. The shank is provided to shear once a predetermined turning torque from the drive member, and hence clamping force, is achieved and the plane of shear can be accurately determined relative to the surface of the article on which the bore is formed and into which the shank is screwed. This is an advantage over the conventional clamping screw which is provided to shear at one fixed weakened location and, when sheared can leave an undesirable protruding portion above the surface of the article. The screw clamping apparatus of this invention allows one size shank to be used for clamping articles to different sizes and the position of the planar shear can be located at a position along the length of the shank, thereby eliminating the occurrence of protrusions when shear occurs.

Abstract: This is a branching connector for establishing a branch connection between a main cable (15) and at least one branch cable (15').In accordance with the invention, at least the projecting part of contact members (17, 65 65') employed for this purpose is embedded in an insulating material dished member (42, 42', 76, 76') adapted to be applied against a cable (15, 15') of this kind all around it and so to seal and protect the electrical contact established between it and this cable (15, 15').Application, inter alia, to the connection of users to overhead electrical power distribution networks.

Abstract: A hot line clamp for temporarily or permanently connecting a branch conductor to a main conductor. The clamp includes a rigid generally U-shaped body with a cylindrical boss for receiving the branch conductor. The branch line is secured in place on the ground by the lineman. The clamp also includes a flap member which is rockably mounted about one leg of the U-shaped body between an open position for enabling the clamp to be received on the main conductor and a closed position for maintaining the clamp in place on the main conductor. A torsion spring is disposed around the pivot for the flap member and biases the latter toward the open position. The edges of flanges on flap member cooperate with the main conductor when the clamp is received thereon for rocking the flap member to the closed position.
