→  Drop-arrester Product Overview
HY5WS-17/50DL-TB drop-out (can be cast type, removable) distribution type arrester is modified zinc oxide surge arresters cleverly installed in the drop-drop-out fuse on the body, to keep power in the case of , you can wind up with the joystick easily insulated arrester testing, repair and replacement, not only to ensure the smooth flow of lines, but also greatly reduce the power and intensity of maintenance staff time, not particularly suitable for places such as post and telecommunications blackout , airport stations, hospitals, downtown business areas. Product performance with other distribution type arrester.
HY5WS-17/50DL-TB increased drop-out arrester device, an exception occurs in the arrester failure, the use of so-frequency short-circuit current from the device action, so that automatically disengaged from the device ground, lightning arrester components turn over, run out to prevent further expansion of the accident, and ease of maintenance personnel to detect maintenance and replacement. The principle is similar turn over the lead melt fuse fuse fuse tube to fall over.
I am using the current type of the most advanced RW12 falling bodies, access to reliable, flexible division, and the use of composite columns and stainless steel cover, advanced accessories, with anti-fouling corrosion, etc., heat from the explosion-type device with fast action, action current range, and can withstand the impact of current regulations and the advantages of load movement.
Product performance to meet the national standard GB11032-2000 (eqvIEC60099-4: 1991) "metal oxide surge arresters without gaps for AC", JB/T8952-2005 "communication system with composite coat metal oxide surge arresters without gaps", GB311.1-1997 " insulation with high voltage power transmission equipment. "

Drop-arrester Features
1. arrester unit may take time loading and unloading, particularly suitable for power should not be the place.
2. with disconnector, arrester unit fails to automatically turn over, quit running, timely maintenance and replacement.
3. unit to fall over due to failure of the formation of clearly marked, easy to find, timely maintenance and replacement.
4. Arrester composite jacket, falling bodies composite pillars, water-repellent, good tolerance ability.

Drop-arrester conditions of use
1. Ambient temperature: -40 鈩 ~ +40 鈩;
2. Altitude less than 3000m;
3. Power Frequency: 48Hz ~ 62Hz;
4. Maximum wind speed does not exceed 35m / s;
5. seismic intensity of 7 degrees and regions.

Drop-arrester USER:
1 arrester installed before use, should be stored in clean, dry room;
2 arrester is put into operation, should be preventive tests
3 Please specify when ordering model, the number of parameters and surge arresters. For special requirements, please indicate in the contract.
4 products from the date of shipment, within one year under normal operating environment can not be used due to quality problems, the company responsible for maintenance and replacement.

Drop-arrester installation instructions
1 This product should be installed at the rated voltage and rated voltage of the same arrester systems and equipment on the line;
2 Check the arrester before installation components and drop-tightness between agencies to ensure good contact and unloading flexible cast.
3 adjustment method: turn on the copper contacts arrester (with pull ring) to the sub-gate pull in 6 ~ 10kg or less, to pay to maintain copper contact ring-pull side outwards, and then tighten the nut, pull the ring is not easy to turn;
4 installation should be made into a plumb line arrester with 15 to 30 degree angle, the distance of not less than 200mm, the phase distance of not less than 350mm;
5 Drop-institutional high-voltage cable termination, the next terminal must be grounded, not reversed;
6. Arrester into operation before and after the note put into operation with distribution type arrester;
7 When the arrester need repair or replacement, in the case of UPS, wind up lever aligned with the insulation on the arrester hooks for convenient unit operation, as the replacement drop-melting tube;
8 units running in the fall arrester, arrester unit should be replaced to restore the system of protection and do not need to replace the falling body, my company can provide the individual arrester units.
