Cable termination with fiber optic temperature sensor

A temperature sensor device for a cable termination, comprising:

• at least one optical fiber configured to be wound around the tubular insulator body, the at least one optical fiber comprising:
• a helically wound first length configured to extend from the base to the top part;
• a helically wound second length configured to extend from the top part to the base;
• and
• a loop portion configured to be positioned near the top part, where the first length joins the second length;
• wherein the first length and the second length are configured to be arranged parallel to each other side by side with an axial spacing therebetween to form successive pairs of coils that are axially spaced from each other by an axial pitch.

A cable termination with stress cone monitoring, comprising:

• a base;
• a top part;
• a tubular insulator body extending along a longitudinal axis between the base and the top part and defining an inner region;
• a connection cable housed within the inner region;
• a stress cone mounted on the connection cable;
• a temperature sensor device configured to detect temperature anomalies associated with the stress cone, the temperature sensor device comprising at least one optical fiber wound around the tubular insulator body, the at least one optical fiber comprising:
• a helically wound first length extending from the base to the top part;
• a helically wound second length extending from the top part to the base;
• and
• a loop portion near the top part, where the first length joins the second length;
• wherein the first length and the second length are arranged parallel to each other side by side with an axial spacing therebetween to form successive pairs of coils that are axially spaced from each other by an axial pitch;
• and an electrically insulating outer sheath covering the tubular insulator body and the at least one optical fiber wound thereon.
