MacLean Power Systems is pleased to introduce high capacity deadend tees for high strength guying and deadending of transmission structures. The galvanized steel deadend tees are rated at 60,000 pounds ultimate tensile strength and are available with a curved or flat mounting base with two different common mounting hole sizes. The mounting hole in the […]

MPS is pleased to introduce and expand our offering of angle crossarm pins with the addition of catalog numbers, P400Z, PA400Z and PA404Z. Attached is our brochure for angle crossarm pins with the new products added. The new P400Z and PA400Z pins with nylon alloy insulator threads have previously been available with lead threads only.

In July, MacLean Power Systems launched a new mold-on polymer fuse cutout design which provides full fault spectrum protection to overhead distribution systems rated 4.16kV through 25kV for use in the electric utility market. The second generation polymer fuse cutout is a protective device for high voltage power lines which operates very similar to the

The 01-M-044 is a multi functional “C` clamp type and rated ASTM 5H. Light and compact with a range from 0.20 / #4 up to 2.5, this clamp is perfect for work on either distribution, transmission and substation. It can be installed on all conductors, apparatus, round bus bar and flat bus base as well

Major areas of concern today with polymer insulators are their service life in contaminated environments and water droplet corona mitigation. In the mid 1990’s MacLean Power Systems started a design initiative to improve all suspension insulator’s performance in these areas. The MPS patented stacked shed design emerged and is now used on all suspension Apex

During and after a storm, utilities have enough issues to deal with without the added stress of worrying about when and where critical products for power restoration are coming from. Power recovery is the highest priority for MacLean Power Systems. We want to take the guesswork and anxiety out of emergency situations by offering the

Porcelain is a ceramic made by heating various raw materials in a kiln. During this process the kiln can reach temperatures of up to 1500 degrees Celsius. After baking, a glassy, translucent product is produced yielding high permeability and a white or off white color. Even though this material is known for its strength, it

Braced Post technology has become the design of choice for transmission lines 138kV to 230kV over the last decade for its economic advantages, construction efficiency, visual aesthetics, and Narrower Right of Way requirements. Combining a line post insulator with a suspension insulator as a direct brace without the use of a davit arm can greatly

MPS grounding clamps have been tested and approved for the revised ASTM F855-2009 for asymmetric fault current with grade 5H and 7H. MPS has grounding products approved for 5H and 7H in substation, transmission and distribution applications. These designs include time proven features of lubrication chamber for upkeep of eyescrew threads and strain relief for

MacLean Power Systems formula suspension clamps are designed to support ACSR and all aluminum conductors without the use of armor rod. Meaningful savings in both material and installation labor can be realized by eliminating the need for formed armor rod. The formula suspension concept is simple: formula clamps offer the conductor substantially increased support areas
