Water-resistant parallel cable systems and methods

An electrical cable, comprising:

• a conductor set comprising:
• a first insulated conductor;
• a second insulated conductor;
• and
• a ground conductor,
• the first insulated conductor, the second insulated conductor, and the ground conductor arranged with the ground conductor positioned between the first insulated conductor and the second insulated conductor;
• and
• a jacket disposed about the conductor set, the jacket comprising:
• a central portion proximate the ground conductor;
• outer portions proximate the first insulated conductor and the second insulated conductor;
• and
• intermediate portions extending between the central portion and the outer portions,
• the central portion having a first thickness, the outer portions having a second thickness, and the first thickness being less than the second thickness, and
• the intermediate portions comprising depressions defining necked sections between the central portion and the outer portions.

A method of forming an electrical cable comprising:

• insulating a first conductor wire to form a first insulated conductor;
• insulating a second conductor wire to form second insulated conductor;
• and
• arranging the first insulated conductor, the second insulated conductor, and a ground conductor with the ground conductor positioned between the first insulated conductor and the second insulated conductor to form a conductor set;
• and
• disposing a jacket about the conductor set, the jacket comprising:
• a central portion proximate the ground conductor;
• outer portions proximate the first insulated conductor and the second insulated conductor;
• and
• intermediate portions extending between the central portion and the outer portions,
• the central portion having a first thickness, the outer portions having a second thickness, and the first thickness being less than the second thickness, and
• the intermediate portions comprising depressions defining necked sections between the central portion and the outer portions.
