Counter-flashing (or cover flashing, cap flashing) is a term used when there are two parallel pieces of flashing employed together [4] such as on a chimney, where the counter-flashing is built into the chimney and overlaps a replaceable piece of base flashing. Strips of lead used for flashing an edge were sometimes called an apron, [5] and the ...
The lead wire is a coated copper wire, a tinned copper wire or another electrically conductive wire used to connect two locations electrically. In electronics, a lead (/ ˈ l iː d /) or pin is an electrical connector consisting of a length of wire or a metal pad (surface-mount technology) that is designed to connect two locations electrically.
Splice site of a copper wire. Cable sleeve (lead sleeve) for connecting paper-insulated wires Insulating sleeves. The splicing of copper wires happens in the following steps: The cores are laid one above the other at the junction. The core insulation is removed. The wires are wrapped two to three times around each other .
In electrical engineering, electrical length is a dimensionless parameter equal to the physical length of an electrical conductor such as a cable or wire, divided by the wavelength of alternating current at a given frequency traveling through the conductor. [1] [2] [3] In other words, it is the length of the conductor measured in wavelengths.

The characteristic impedance of twin lead is a function of the insulating material and its thickness, and the wire diameter and its spacing; in the most common type, 300 Ω twin-lead ribbon cable, the wire is usually AWG 20 or 22 (0.52 or 0.33 mm²), about 7.5 millimetres (0.30 in) apart.
Galloping conductors in eastern Idaho around Christmastime 1998. Conductor gallop is the high-amplitude, low-frequency oscillation of overhead power lines due to wind. [1] The movement of the wires occurs most commonly in the vertical plane, although horizontal or rotational motion is also possible.
