Embodiment Construction

[0015] As reference is made to several figures, the same reference numerals refer to the same parts. figure 1 There is shown a sealing device 20 for insulating and sealing a circuit joint between an elongated metal wire or strip anode 22 and an elongated electrical conductor, such as an electrical cable 24 . Additional details of anode 22 and cable 24 will be described below. In order to meet the requirements, the anode 22 is a slender and thin flexible element, such as a wire, a strip, a tube, etc., and the anode 22 can appear in any common structure, and is made of a conductive material, such as a mixture of noble metals, such as titanium. Based mixed metal oxide (MMO) or niobium / copper based platinum, or other common anode materials. Cable 24 may also be present in any conventional configuration. As described in the embodiment, the cable 24 comprises various electrical conductors, such as copper, stranded wires or wires 24A having an electrically insulating sheath or coat...

Abstract

A sealing device for insulating and sealing a circuit joint connecting a metal linear or strip-shaped anode and a cable and a manufacturing method thereof. The cables are insulated except for the open area connected to the wire anode. The sealing device comprises a body of insulating material formed in situ at the location of the electrical circuit joint, said body being adapted to completely cover the joint and in combination with the portion of the electrical insulation attached to the joint to insulate the joint and protect it from water or other substances Infiltrate the joint.

Description

technical field [0001] This invention relates to cathodic protection systems and, more particularly, to equipment for insulating and sealing electrical connections between linear or strip anodes and cables or other structures requiring protection. Background technique [0002] When wire and rod anodes are connected to the leads or conductor cables of an anode / anode assembly, the connection or joint must be both electrically reliable and waterproof. If the joints are not waterproof, there is an inevitable risk of joint failure. To this end, various methods have been attempted for sealing the circuit joints and isolating them from the surrounding environment. Connection failures usually occur because the anode connection is almost always in an electrolyte, such as soil or water. When DC current flows through a circuit connector and it is exposed to moisture or soil, the connector is susceptible to corrosion and failure. Where the structure to be protected includes cables an...
