Abstract: The present disclosure relates to a cable termination comprising: a base; a top part; a tubular insulator body extending according to a longitudinal axis (A1) between the base and the top part; a temperature sensor device for measuring temperatures along the cable termination, comprising at least one optical fiber wound around the tubular insulation body; and an electrically insulating outer sheath covering the tubular insulator body and the at least one optical fiber wound thereon, wherein the at least one optical fiber comprises 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 parallelly arranged side by side spaced with an axial spacing (?z), forming subsequent couples of coils axially spaced with an axial pitch (?p).

Abstract: Insulator for a cable termination assembly comprising: a main body of insulating material extending along a longitudinal direction X and having a cylindrically symmetrical shape with a first longitudinal end and a second longitudinal end opposite to each other, said main body being adapted to be fitted on a power cable; a ring-shaped electrode made of a mesh of conducting material integrated in the main body at a predefined distance from the first end, said ring-shaped electrode being configured to be connected to an external voltage detector.

Abstract: A shrinkable cable joint includes a joint insulating layer that surrounds a connection region configured to house two connected cable ends. A joint semiconductive layer surrounds the joint insulating layer. A joint screen layer surrounds the joint semiconductive layer. A joint sheath surrounds the joint screen layer. A capacitive voltage sensor is arranged between the joint screen layer and the joint semiconductive layer. The capacitive voltage sensor includes a sensor insulating layer having a first side and an opposite second side; a sensor electrode and a guard electrode arranged on the second side and directly contacting the joint semiconductive layer; and a sensor conductive layer arranged on the first side. The sensor conductive layer includes a first conductive layer portion in direct contact with the joint screen layer and electrically coupled to the guard electrode and a second conductive layer portion electrically coupled to the sensor electrode.

Abstract: A boiler has a combustion chamber wherein combustion occurs under high turbulence and wherein the combustion products in the form of smoke are exhausted from the boiler in proximity to the liquid to be heated in a manner whereby the risk of the smoke path being clogged by soot is eliminated so that pollution of the ambient atmosphere is negligible. The burner-operated boiler has a combustion chamber which, at least in front of the burner, is defined by a concave wall section having its concavity facing the burner. In this manner, a recirculation of a portion of the smoke is obtained in the combustion chamber creating a high turbulent condition thereby facilitating complete combustion. The smoke is discharged from the combustion chamber into a smoke sleeve have a substantially annular shape with a vertical axis wherein the only horizontal wall on which deposition of soot may occur is very small.
