Product features :
Pulling Eye provides positive hotstick operation. The pulling eye strength exceeds 500 lbs of force. Insulation consists of peroxide-cured EPDM rubber that offers proven, uncompromised reliability and dimensional stability.
Molded Shield of conductive peroxide-cured EPDM rubber meets all requirements of IEEE Std. 592 for exposed semi-conducting shields.
Drain Wire Tab provides a contact point to attach a #14 ground wire to ensure the shield is at ground potential and maintains deadfront construction.
Fiberglass Wrap ensures that the MOV block stack remains in one piece and prevents the blocks from breaching the side wall should the arrester fail.
ID Band provides clear visual identification of arrester MCOV and duty cycle ratings.
Flexible Lead is #4 AWG copper rope lay conductor 595 strand (7 x 85). Ends are soldered to prevent fraying. Standard length is 36” long. Other lead lengths are available.
MOV Blocks are the same ones found in Ohio Brass overhead arresters.
application:
Our parkingstand and elbow lightning arresters are designed to mate with 200 amp loadbreak interfaces that conform to IEEE Std. 386. The parkingstand lightning arrester contains a defined interface, while the elbow lightning arrester mates with a defined interface.
The arrester installed at the end of a radial system or at both ends of an open point in a loop circuit will provide excellent protection against high voltage surges resulting from lightning or switching.
When combined with an Ohio Brass PVR (Riser Pole) arrester, optimum protection can be achieved. Our arresters are fully shielded and submersible, either contin.
