Fall Arrester

The HY5WS-17/50DL-TB drop-type lightning arrester is a modified distribution zinc oxide arrester cleverly integrated into thedrop-type structure of the fuse, allowing for easy inspection, maintenance, and replacement using an insulating switch rodwithout interrupting power supply,. This not only ensures the uninterrupted operation of the line but also significantly reducesthe workload and time required by maintenance crews. It is especially suitable for locations where power outages areundesirable, such as postal and telecommunications facilities, airports, stations, hospitals, and bustling commercial areas. Theperformance of this product is identical to that of a distribution arrester. The second-generation drop-type arrester features adisconnector. in the event of an arrester malfunction, the disconnector is activated by the power frequency short-circuitcurrent, causing the disconnector's ground terminal to automatically disconnect, This allows the arrester components to fipdown and deactivate, preventing further accidents and facilitating timely maintenance and replacement by maintenancepersonnel. The flipping mechanism is akin to that of a fuse causing the fuse tube to flip due to the melting of the fuse wire.Our company utilizes the world's most advanced RW12 drop mechanism,characterized by reliable contact,flexible switchingand advanced components including non-rusting steel covers with composite pillars. lt offers anti-pollution capabilities, rapidresponse, a wide current range, and can withstand specified current surges and operational loads, The product performancemeets the national standard GB11032-2000 (egv!EC60099-4:1991) Metal-oxide Surge Arresters without Gaps for A.c, systemsJB/T8952-2005 Metal Oxide Surge Arrester with Seamless Outer Cover for Communication System and GB311.1-1997iInsulation Coordination of High Voltage Power Transmission and Transformation Equipment.

1. The arrester unit can be electrically loaded and unloaded at any time, making it ideal for locations where power outages
are not advisable.
2. Equipped with a disconnector, the arrester unit automatically flips down and deactivates in the event of a fault, ensuring
the line remains operational.
3. The unit's flipping down upon malfunction creates a conspicuous sign, facilitating timely detection and subsequent repair
or replacement.
4. The lightning arrester adopts a composite jacket, and the drop mechanism adopts a composite pillar, which has good
hydrophobicity and strong pollution resistance.

1.Ambient temperature:-40C~+40°C;
2. The altitude is not more than 3000m;
3.Power frequency:48Hz~62Hz;

Notes: The parameters of this lightning arrester are consistent with conventional models, and the aforementioned
modelis for distribution purposes; it can be substituted with other types such as the capacitor model.

1. This product should be installed on circuits with a rated voltage consistent with that of the lightning arrester.
2. Before installing and using, check the tightness between the lightning arrester components and the dropmechanism to ensure good contact and flexible operation.
3.Adjustment method: Rotate the copper contact (with a pull ring) on the lightning arrester to set its openingtension within 6-10kg, ensuring that the pull ring side of the copper contact points outward. Then tighten the lower nut to secure the pull ring.
4.During installation, angle the lightning arrester at 15-30 degrees relative to the vertical, maintaining a distance of at least 200mm.
