(3) Apply a good flux such as stearine.

(4) Apply solder and heat to a point where it is pliable.

(5) Work solder into sheath with a paddle or stick and smooth.

(6) Wipe with wiping pad.

d. Concentric-neutral cable construction. The neutral conductor of this type of cable consists of equally spaced strands of wire or flat strap wrapped spirally around the outside of the cable insulation. Concentric neutral cables may be of a single or multiple conductor configuration and may have an outer protective jacket over the neutral conductors. Care must be used in handling the cable to prevent the concentric-neutral conductors from loosening or bunching together in one place around the cable circumference. If this occurs, it may cause tracking of the insulation or affect the voltage stress distri­bution within the insulation. The number and size of the concentric conductors are determined by the manufacturer in accordance with ICEA standards. Repairs should ensure that the operating character­istics of the concentric neutral are not adversely affected.

e. Gas-pressurized cable. Repairs may be re­quired for this cable because of a loss of pressure from a leak in the outer covering or conduit or a puncture in the solid dielectric cable.

(1) Gas pressure. The high density of the gas may result in a zero gage reading even though suf­ficient gas is still present to keep out air and mois­ture. If the cable is under a water-pressure static-head, then a pressure of 0.5 pounds per square inch gage (3.5 kilopascals gage) is needed for each foot (0.3 meters) of water head to continue to keep water out.

(2) Repair of gas Leaks.
