The skate line industry began to update on the standard

Update time:2018-11-14 11:29:17Clicks:5770
Now an emerging power supply system slip line has appeared, gradually applied to the production of angle steel safety slide lines to H-type safety slide lines, and has been technically improved, the industry standards have also been updated.
Now an emerging power supply system slip line has appeared, gradually applied to the production of angle steel safety slide lines to H-type safety slide lines, and has been technically improved, the industry standards have also been updated, As for the latest standards that appear, here are some:
1. Since the use of the sliding line transmission device is not limited to cranes, it is widely used in various industries, so the name eliminates the prefix of “crane”;
2. Rated voltage AC 1200V and below or DC 1500V and below is changed to AC 1000V and below or DC 1500V or less;
3. The nominal cross-sectional area of the transmission conductor (mm2) is changed from 1000mm2 to 3200mm2;
4. Add Table 1 “Transition Rate Conversion Coefficient under Different Node Sustainability Rate”;
5, the insulation material resistance to abnormal heat and fire hazard test using Bunsen burner method to change the glow wire test;
6. In Table 8, “Dielectric test voltage corresponding to the rated insulation voltage”, the AC voltage test is reduced, and the DC test voltage is increased;
7. Increase the running performance test of the collector;
8. The rated short-time withstand current RMS should not be less than 20 times the rated current should not be less than 10 times the rated current.
