Some phases of electrical testing by in a rubber covered wire plant

DEVELOPMENT of new machines and processes for the manufacture of rubber covered wire made possible “straight line” production methods, with the elimination of process stocks and storage. However, the advantages of this method of production were reduced by the fact that the standard water test applied to the finished wire did not lend itself to this method of production. With this process a stock of wire must be kept in the test tanks for a minimum 12-hr period, and stored in racks for an additional drying period. This requires stocks of process material, and in addition, the water test equipment requires a relatively large area; also separate equipment is necessary for coiling the tested wire
