[en] The design and manufacturing technology of unified modules of wire spark chambers (WSC) with the electrodes of about 2 x 2 mm² are described. They serve as basic track detectors in the WSC systems worked out at IHEP. At present more than 130 modules of WSC of different dimensions and total number of information wires of 100.000 are used in the experiments performed at the IHEP 70 Gev accelerator. The WSC unified module consists of ferritecore memory device, wire electrodes and a high-voltage feeder. The unification principle used in the design and common technological process in manufacturing the WSC modules allows one to achieve a high reproduction degree of chambers characteristics in various WSC systems. It has been confirmed with a three year period of exploiting the WSC in experiments
