Product descriptions from the supplier
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.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
Understanding Transformer Neutral GroundingI. What is a Neutral Point?In transformers and generators, the neutral point is a specific point in the winding where the absolute voltage between this point and each external terminal is equal. In the diagram below, pointOrepresents the neutral point.II.

What’s the Difference Between Rectifier Transformers and Power Transformers?What is a Rectifier Transformer?"Power conversion" is a general term encompassing rectification, inversion, and frequency conversion, with rectification being the most widely used among them. Rectifier equipment converts input AC power into DC output through rectification and filtering. A rectifier transformer serves as the power supply transformer for such rectifier equipment. In industrial applications, most DC power supplies are obtained by combining a rectifier transformer with rectifier equ01/29/2026
