Stainless Steel Adjustable Swaged Sockets

Depending on cable diameter two types of stainless-steel socket could be applied. For the smaller cable diameter, the stainless steel swaged sockets made of X2CrNiMoN22-5-3 or equivalent material are the best option.  For the cable with bigger diameter the stainless steel sockets made of X4CrNiMo 16-5-1 or equivalent material are most suitable.

 Cables are terminated to the sockets by means of two possible methods:

•  Socketing by polyester resin for structural use with minimum 100% efficiency to the strand minimum breaking force. In accordance with EN 13411-4.
• Swaged (pressed) socketing with minimum 90% efficiency to the strand minimum breaking force. In accordance with EN 13411-8.

 Socketing by swaging is performed by pressing the section of sockets with the cable termination inside. This method reduces the cable system’s resistance by 10% of strand minimum breaking force. Spelter socketing involves the following manufacturing operations:

1. The wires at the strand end are opened to form a “brush”.
2. The brush is ultrasonically cleaned.
3. The brush is positioned inside the internal cone profile of the socket.
4. Structural polyester resin or zinc / zinc alloy is poured into the socket wires to form asocket cone.
5. The solid cone that is created transfers the load between cable and socket.

There are no mechanical wedges, grips, serrations or connections used in the socketing process, meaning there is no mechanical damaging of the wires within the strands at this safety critical area. All sockets connections are designed to have a breaking force higher than that of the respective strand.
