根据矿山机械供电电缆常作远距离输送电力,以及经常收绕和拖出等特点,我们专为直径在12.7～76.2毫米范围内的这种电缆,设计了模拟电缆现场条件的试验设备。这种液压传动试验机可根据电缆直径的不同,能使被试电缆做到:(1)绕过若干个不同直径、不同包角的滑轮运转;(2)在0～61米/分速度下进行试验;(3)在静拉力和动拉力下进行试验;(4)按规定的循环次数作正反向弯曲试验;(5)保持电缆连续供电。试验机除了使电 According to the long-distance transmission power of mining machinery power cables and the characteristics of frequent winding and towing, we specially designed the test equipment for simulating the field conditions of cables for cables of 12.7 ~ 76.2mm in diameter. This hydraulic transmission testing machine according to the different cable diameters, can make the test cable to do: (1) around a number of different diameter, different angle of the pulley operation; (2) at 0 ~ 61 m / min speed Test; (3) under static tension and dynamic tension test; (4) according to the provisions of the number of cycles for positive and negative bending test; (5) to maintain continuous cable power supply. Test machine in addition to electricity
