Abstract: A pressurizable telephone load coil assembly is made by placing groups of load coils in enclosure packages, connecting conductors of a length of telephone cable to the load coils, binding the enclosure packages together, placing the bound enclosure packages in a closed end heat-shrinkable tube, encapsulating the enclosure packages, and heat shrinking the open end of the tube over hot-melt glue applied to the end of the length of telephone cable. A heat shrinkable cap including an air valve is shrunk over the opposite end the length of telephone cable to pressurize the load coil assembly to exclude moisture until the telephone cable is spliced into a pressurized telephone system.
