Abstract

An armoured cable termination system and method of assembly is provided that clamps the armour wires of the cable over and around the back of a conical inner armour clamp member. The wires are also retained between the inner clamp member and an outer body and a securing end plate. The armour wires are splayed by the inner clamp member, which is forced onto the cable to displace the armour wires. The forcing mechanism is used to support an armour wire former that bends the armour wires around the back of the inner clamp member. The top clamp is then forced onto the termination assembly, such that the armour wires adopt a smooth curve around the back of the inner clamp and are securely clamped along their length. The assembly may then be mounted to a flexible pulling head for pulling it into contact with a structure.

Claims16

Dependent claims

A terminated cable comprising an armoured cable having an inner component and an armour layer arranged around the inner component;

and a termination assembly, the termination assembly comprising:
a first clamping member comprising an inner channel having at least a portion tapering to a larger diameter at one end, the cable passing through the inner channel;
a second clamping member having a central channel and a tapered outer portion lying at least partially within the inner channel of the first clamping member, the tapered outer portion extending to a generally curved portion on one end of the second clamping member, the armour layer being splayed away from the inner component, without passing through the central channel, to pass between along the tapered outer portion and the inner channel, and continuing around the curved portion to bend back on itself, the armour layer being retained between the first clamping member and the second clamping member;
and
an end cap comprising a recessed curved portion which engages the armour layer where it passes around the curved portion of the second clamping member, to clamp the armour layer between the curved portion of the second clamping member and the recessed curved portion of the end cap.
