Multi Tubular Gauntlets (PT Bags)

Dynasty Electronics was founded by a team of experts from various fields like battery, textile and chemical industries and other engineering sectors, with a goal of manufacturing high quality Multi Tubular Gauntlets (PT bags) for lead acid batteries in India. These are woven on Sulzer (Switzerland) weaving technology by using selected chlorine-free, 100% polyester, high tenacity yarn. Impregnation by synthetic resin gives very high resistance to acid and chemical oxidation. The multi tubular gauntlet was invented in USA in early 1900s and spread all over the world in the 1920s. At the beginning it was made from PVC and fibreglass, which was than replaced by woven gauntlet, made of polyester yarn. The main advantage of the positive tubular plates is the long service life compared to flat paste plates. Quality of multi tubular gauntlet mainly depends on: selection of raw material; and structure and design. The use of 100% polyester, high tenacity chlorine free yarn allows the multi tubular gauntlets to withstand with the cyclic expansion of active material. The engineered fabrics coated with synthetic resin, which can give the stiffness and enhanced oxidation resistance to the multi tubular gauntlet. Designing and weaving is the other crucial stage in manufacturing of gauntlets. Fine weave of the fabrics give unique porosity and high mechanical strength. Half insulation of gauntlet is the other important criteria in multi tubular gauntlet to prevent lateral short-circuit along the side. Resultant of world class weaving technology, the gauntlet inhibits the shedding but allows electrolyte to freely penetrate in to the active material. It is therefore highly recommended for heavy duty applications where the reduced internal resistance results in improved performance.
