Abstract
A method of forming a plurality of individual heating cables sets includes creating at least a portion of a master cable set by coupling alternating sections of cold and hot cable section, each section of cold cable section having a length twice a model cold cable section length and each section of hot cable section having a length twice a model hot cable section length. A continuous metallic ground sheath is applied about substantially all of the master cable set and a continuous outer jacket is applied about the continuous metallic ground sheath. The master cable set is segmented at defined locations to create a plurality of individual heating cable sets having an overall length of the model hot cable section length plus the model cold cable section length.

A method of forming a plurality of individual heating cable sets, the method comprising:
- creating at least a portion of a master cable set by:
- obtaining a first segment of cold cable section having a length at least a model cold cable section length;
- obtaining a first segment of hot cable section having a length at least a model hot cable section length;
- coupling the first segment of hot cable section to the first segment of cold cable section;
- obtaining a second segment of cold cable section having a length at least the model cold cable section length;
- coupling the second segment of cold cable section to the first segment of hot cable section;
- obtaining a second segment of hot cable section having a length at least the model hot cable section length;
- coupling the second segment of hot cable section to the second segment of cold cable section;
- applying a continuous metallic ground sheath about substantially all of the master cable set;
- applying a continuous outer jacket about the continuous metallic ground sheath;
- and
- segmenting the master cable set at defined locations to create a plurality of individual heating cable sets having an overall length of the model hot cable section length plus the model cold cable section length.
A method of forming a heating cable set, the method comprising:
- obtaining a hot conductor having an outside diameter and a model hot cable section length;
- installing a hot conductor insulation having an outside diameter about the hot conductor to form a hot cable section;
- obtaining a cold conductor having an outside diameter and a model cold cable section length;
- installing a cold conductor insulation having an outside diameter about the cold conductor to form a cold cable section;
- varying at least one of:
- i) the outside diameter of the hot conductor;
- ii) the outside diameter of the hot conductor insulation;
- iii) the outside diameter of the cold conductor;
- and iv) the outside diameter of the cold conductor insulation to achieve a difference between an outside diameter of the hot cable section and an outside diameter of the cold cable section that is within a predetermined target range;
- and
- coupling the at least one hot cable section to the at least one cold cable section to form a heating cable set having a finished length of the model hot cable section length plus the model cold cable section length.
A continuous heating cable assembly, comprising:
- a first length of cold cable section having a length twice a model cold cable section length;
- a first length of hot cable section having a length twice a model hot cable section length, the first length of hot cable section being coupled to the first length of cold cable section;
- a second length of cold cable section having a length twice the model cold cable section length, the second length of cold cable section being coupled to the first length of hot cable section;
- a second length of hot cable section having a length twice the model hot cable section length, the second length of hot cable section being coupled to the second length of cold cable section;
- a continuous metallic ground sheath applied about a cumulative length of the hot cable sections and cold cable sections;
- and
- a continuous outer jacket applied about the continuous metallic ground sheath.
