LBT-JY Wire and Cable Insulation Thickness Gauge
The wire and cable insulation thickness gauge is used to measure the insulation and sheath thickness of wires and cables. It is a precision optical measuring instrument integrating photoelectric technology, widely employed across various industries—including machinery, instrumentation, electronics, cable manufacturing, rubber, plastic packaging, and bearings—as well as in metrology rooms, laboratories, and production workshops of research institutes and metrology‑verification agencies. This instrument can efficiently inspect the contour dimensions and surface profiles of workpieces with complex geometries.
LBT-2501 Wire and Cable Heat Release Rate Test Apparatus
This standard specifies the test apparatus and test methods for evaluating the flame spread, heat release, and smoke production characteristics of vertically installed bundled wires, cables, or optical cables under specified test conditions. The tests enable determination of the heat release rate (HRR), total heat release (THR), smoke production rate (SPR), total smoke production (TSP), fire growth rate index (FIGRA), as well as the characteristics of burning droplets and particulates.
LBT-2502 Wire and Cable Vertical Burning Tester
The vertical flame‑spread tester for wires and cables is used to determine the non‑propagating‑flame performance of single‑core plastic wires, control cables, cross‑linked cables, elevator cables, marine cables, mining cables, and similar products. It can also be employed for vertical flame‑spread testing of highly self‑extinguishing, low‑smoke, halogen‑free flame‑retardant polyolefin insulation compounds, as well as 105°C low‑smoke, halogen‑free flame‑retardant irradiated polyolefin insulation materials.
LBT-2503 Cable Bundle Burning Tester
The bundled wire and cable combustion tester is an instrument used to evaluate the ability of vertically installed bundled cables or optical cables to inhibit the vertical spread of flame under specified conditions. It is an essential device for conducting bundled‑cable combustion tests on power cables, control cables, optical cables, and similar products. When a predetermined volume of gas is supplied to the test chamber and a standard ignition source is employed, this instrument can be used to assess the vertical flame propagation along vertically oriented cables and wires.
LBT-2505 Wire and Cable Smoke Density Tester
The national cable industry is vigorously promoting the development of low-smoke, halogen-free cables and materials. These products all require measurement of smoke density. The primary principle behind smoke-density measurement is that, within a defined chamber, a cable or material generates smoke under specified combustion or radiant‑heat conditions. As a light beam passes through the smoke, it experiences attenuation; by measuring the beam’s transmittance and performing calculations, both the optical density and the smoke density are determined.
Wire and Cable Electrical Bridge Fixture for Two‑Arm Measurement of Conductor Resistance
The bridge fixture is suitable for measuring the DC resistance of various power cables and electrical‑equipment cables as specified in GB/T 3048, “Test Methods for Electrical Properties of Wires and Cables,” and can also be used to measure the DC resistance of other conductive materials. To ensure the fixture fully complies with the standard’s requirements, it adopts a quick‑clamping and release mechanism based on threaded screws, along with separate mechanical structures for the voltage and current terminals, thereby guaranteeing reliable contact between its four‑terminal configuration and the device under test. The fixture features an aluminum alloy extruded base plate, offering a well‑designed structure that is both convenient and easy to use.
It is used to determine the micro‑Deval abrasion value of coarse and fine aggregates, thereby evaluating their resistance to wear. The machine features a heightened design for greater convenience during testing; it comes standard with four stainless steel test cylinders having smooth inner surfaces. Speed is controlled by a microcomputer, ensuring precise rotation counts, and users can set both the number of rotations and the duration, with the device automatically stopping once the specified values are reached.
