[1] [2] [3] These links, known as WECC Intertie Paths, are not necessarily single transmission line, rather they are interties between various areas. These areas can be quite distant, such as Path 65 between The Dalles, Oregon and Los Angeles, California or short such as Path 62 between Southern California Edison's Eldorado and LADWP's ...
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires. [1] Cable reels, which can also be termed as drums, have been used for many years to transport electric cables, fiber optic cables [ 2 ] and wire products.
A tie line, also known as a tie trunk, is a telecommunication circuit between two telephone exchanges or two extensions of a private telephone system. [1] [2]
An interconnector (also known as a DC tie in the USA [1]) is a structure which enables high voltage DC electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids .
A 15 kV transmission line, approximately 175 km long, connected Lauffen on the Neckar and Frankfurt. [10] [19] Transmission voltages increased throughout the 20th century. By 1914, fifty-five transmission systems operating at more than 70 kV were in service. The highest voltage then used was 150 kV. [20]
High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.
Cable entries are offered in different sizes, but most of them are based on cut-out dimensions and drilling templates for standard industrial connectors (10-pin, 16-pin, 24-pin). Round cable entry plates are usually produced in metric standard sizes (M16 – M63)
