Unidirectional Scraper Tester for Enamelled cables

ST-6604Q Unidirectional Scraper Tester (Enamelled wires) Standards: According to clause 6 of IEC 60851-3:2009, clause 3.59 of NEMA MW 1000 part 3, GB/T4074.3: 2008, GB/T 6109-2008 and JIS3003 etc. Used range: Applied to detection of flat wire (0.800-5.600mm narrow width type) and enamelled round wire (ф0.100-5.000mm) coating and cable insulation and character Scratch resistance test Features:  Detection the scrape resistance of enamelled wires (diameter of more than 0.250mm (including 0.250mm)  Every 120o to scraper f  or each sample, total rotation 2 times, like 120o and 240o from the original point.  The height of supporting anvil can be adjusted upper and down to meet difference size of test samples.  Samples straight device and not more than 1% Technical parameters： 1. Enamelled wires diameter range: 0.250~2.500mm 2. Scrape head: ф0.23 ± 0.01 made by polished piano wire as the scrape needle 3. Scrape moving speed: 400±40mm/min 4. Test voltage: 6.5±0.5V/DC 5. Test current: ≤20mA 6. When the scrape needle touch the conductor will stop and alarm automatically (touch conductor length not more than 3mm). 7. Scrape head moving space:>100mm 8. Scratched error: ±5%； 9. Power supply: AC220V±10%, 50HZ, or as actual demand to design
