The Armor Survivability Kit consisted of armored steel doors with bullet-proof glass, protective armored plating, and a ballistic windshield and came in either a two-door kit variant (weighing 900 pounds/409 kilograms) or a four-door kit variant (weighing 1,300 pounds/590 kilograms).
In electrical power distribution, armoured cable usually means steel wire armoured cable (SWA) which is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.
This kit was designed and tested by the U.S. Army Research Laboratory at Aberdeen Proving Ground, MD. [2] The ballistic threats encountered at the time of development exceeded the design limits of the baseline M1114; therefore, the Frag 5 doors were developed. [2] They provided additional protection from roadside bombs designed to pierce tank ...
Figure parts A–D show steps in forming a "short tie" Western Union splice. Figure parts E and F show two possible "long tie" variations.

It is the preferred method of bonding, and indeed it is the only acceptable means of bonding copper to galvanized cable. [5] The NEC does not require such exothermically welded connections to be listed or labelled, but some engineering specifications require that completed exothermic welds be examined using X-ray equipment.
