The present invention discloses a bracket (1) with enhanced loadbearing capacity for power transmission poles wherein protrusions (52) extending from loadbearing plates (12, 13) are inserted into horizontal and parallel slots made in the base plate (11), and protrusions (52) are bent behind the base plate (11). After insertion and bending, protrusions (52) portion of loadbearing plates (12, 13) are secured by welding on both sides namely the front and rear of the base plate (11). The bending of protrusions of loadbearing plates (12, 13) behind the base plate (11) and welding it on both sides considerably improve the strength of the joint, and thus the loadbearing capacity of the bracket is significantly enhanced.

A clamp-type line post insulator is disclosed. The clamp-type line insulator is provided with a thread clamping device, and comprises: a body, a cable clamp, an insulation unit and an adjustable fixing unit. In the present invention, the body comprises: a receiving recess, a fixing base and a cable groove. Moreover, a pivoting end of the cable clamp pivotally connected to a pivot member that is formed on the fixing base. Particularly, after placing an electrical cable in the cable groove, the cable clamp is rotated by taking the pivot member as an axle center, thereby inserting an engaging end of the cable clamp into the engagement groove to engage with it. By such arrangements, the electrical cable be pressed and fixed in the cable groove by rotating the adjustable fixing unit.

An eddy current energy-dissipating spacer is mainly composed of a spacer frame, a conductor clamp and energy-dissipating elements. The eddy current energy-dissipating spacer not only provides the function of an ordinary spacer, but also reduces the vibration of the transmission lines; and at the same time, can effectively reduce the vibration of the transmission lines, especially the torsional vibration by adopting the eddy current and viscoelastic material for energy dissipation; improves the eddy current strength by adjusting the gear radius ratio, thus increasing the damping force; can adjust the damping parameters by adjusting the magnetic field strength of the permanent magnet; can produce long-term stable vibration reduction effect by adopting the permanent magnet to provide continuous magnetic field without additional external energy input; can effectively avoid the magnetic flux leakage of magnetic circuits by adopting the magnetic material.

An insulator includes an end fitting and a connecting device disposed on the end fitting for connecting the insulator to a suspension device. The insulator also includes an additional operating device. The end fitting and the connecting device are formed in one piece. An arrangement is also provided for dissipating overvoltage using the insulator according to the invention.
