For certain locations it may be important to use a cable which retards flame in case of fire and is self – extinguishing when the source of fire is removed. This test is carried out on finished cables to verify this property. For certain locations it may be important to use a cable which retards flame in case of fire and is self – extinguishing when the source of fire is removed. This test is carried out on finished cables to verify this property. The sample cable is hanged in the chamber and is burned through the burner provided in the instrument for the prescribed time. After the flame is removed, the period of burning of cable is noted by a stop watch. After the cable ceases to burn, the effected area is measured through the scales provided in the chamber.

The Instruments is used for heat Ageing test under oxygen air pressure for insulation & sheath of electric cables. This apparatus is also used for estimating the relative resistance of vulcanized rubber to age determination by assessment of change in tensile strength & elongation of material by subjecting them to accelerated ageing in oxygen air pressure. The instrument is manufactured for Thermal Ageing test under oxygen air pressure for insulation & sheath of electric cables. This apparatus is also used for estimating the relative resistance of vulcanized rubber to age determination by assessment of change in tensile strength & elongation of material by subjecting them to accelerated ageing in oxygen air pressure.

Laboratory Hot Set Test Apparatus is designed to determine the elongation & permanent set of insulation of armored and unarmored single, twin, three , four and multi-core cross linked Polyethylene (XLPE) insulated & PVC sheathed cables for electric supply and control purposes under specified conditions of load temperature and air flow. Laboratory Hot Set Test Apparatus is designed to determine the elongation & permanent set of insulation of armored and unarmored single, twin, three , four and multi-core cross linked Polyethylene (XLPE) insulated & PVC sheathed cables for electric supply and control purposes under specified conditions of load temperature and air flow, as specified in IS: 7098.

The procedure of test for cracking due to environmental stresses on electric polyethylene insulation or sheath of cables. The procedure of test for cracking due to environmental stresses on electric polyethylene insulation or sheath of cables. Certain polar liquids, such as greases and lubricants, when come in contact with either polyethylene sheath or insulation cause cracks, This phenomenon is termed as environmental stress cracking and the degree of cracking is dependent on melt flow index of the polyethylene compound used. This test indicates whether correct grade of polyethylene compound has been used or not.

Two Roll Mill is used for mixing two or more compounds in a homogeneous mixture. This Mixture is then molded into samples for further testing.

For preparing test sample from two or more materials, they have to be mixed homogeneously. The Two Roll Mill with its two heated rollers, rotating in different directions, at slightly different speeds is an ideal machine for such a work. The test samples can then be obtained from the sheet by using Hydraulic Hot Press, Dumb-bell Dies etc.

Two Roll Mill is available in various models for specific customer requirement.
