Bare wire mandrel winding and torsion tester is used for copper rods, aluminium rods, steel wires mandrel winding and torsion tests under the specified torsion speed; as well as test of broken resistance strength and torsion frequency performance for different metal wires, and toughness and adhesion performance for overhead wire and galvanized steel wire. Test method is to clamp the both ends of the specimen, one end is fixed and the other end 360º continuously twisted.
Bridge fixture in line with the amended GB/T 3048 standard requirements of conductor resistance test: The distance from each end of the potential fixture head and the current fixture head is not less than 1-5 times of sample cross-section perimeter, according to usage, it is sorted as bare conductors series and stranded conductors series.
Bunched Cable Vertical Flame Spread Tester tester is used to detect vertically mounted under specified conditions for vertical flame spread inhibiting the ability of bundle cable or fiber optic cable.
Cable Semi Conducting Rubbers and Plastics Resistivity Tester a microcomputer controlled test instrument applied to test the volume resistivity of rubbers and plastics. It is based on the microcomputer principles, automatically test the semi-conducting rubbers and plastics volume resistivity, after testing the resistance, and then input the sample thickness values, the instrument automatically displays the volume resistivity measurement values. No need to manual calculations, with features of high accuracy, good stability, compact structure, and easy to operate. It is the best test instrument for it so far.
Cold Bend Test Apparatus conforms to the standard requirements of IEC540. It is used for cold bend test of the circular insulation wire core whose diameter is small and the sector-shaped insulation wire core which cannot be used for dumbbell. The apparatus shall be held in a refrigerator before and during the test. The diameter of the mandrel shall be between 4 and 5 times the diameter of the test piece (see below).The mandrel shall be uniformly rotated at a rate of one revolution in about 5 s and the number of turns shall be as specified in the following table.
Cold Tensile Testing Equipment, conforms to the standard requirement ofIEC60811-1-4 clause 8.3 and 8.4, common test methods for insulating and sheathing materials of electric and optical cables-part 1-4:Methods for general application-Test at low temperature. It is applicable for the insulating sheath of the high polymer material, electric wire, rubber, and plastic to do the tensile test at the environment of -35°~0°.
Computer-controlled electronic tensile tester (large deformation) is widely used for hardware, metal, rubber and plastics, footwear, leather, clothing, textiles, insulators, wires, cables, terminals and other types of materials, to test tensile, tear, peel, compression, bending and other materials research and development, inspection and test, with multiple functions, wide range of uses. The computer-controlled electronic tensile tester (large deformation) is adopted aluminium alloy enclosure, with lightweight body, beautiful appearance.
Digital Profile Projector high-precision projector is a highly efficient measuring instrument integrating light, machine and electricity. It can be widely used for industries such as mold manufacturing, metal work pressing, electronics, instrument, horologe, as well in universities, research institutes and metering examination departments.
