Technical Information Description and Selection Husky Wire Basket Techtray is a wire mesh cable tray system that utilizes high mechanical strength steel wire that is welded into a 2” x 2” grid system. Typically used to carry data communication and ber optic cables, with a high degree of exibility during installation due to capability and ease of fabricating ttings in the eld. Husky Pan Tray Husky Way straight sections are one piece formed pan that provides a smooth at bottom and a ll depth that is almost the same as the outside height of the tray. With a cover it provides complete...

Technical Information Description and Selection NEMA LOAD CLASSIFICATION The National Electrical Manufacturers Association (NEMA) has standardized the classication of cable tray based on the load to be carried per foot, and the distance between span supports. The load per foot should include not only the cable, but additional load factors for wind, snow, ice, etc. For more information on loading, see page 14 in this section. NEMA CLASS SUPPORT SPAN (feet/meters) MP Husky manufactures Cable Tray in accordance with the latest NEMA Standards Publication VE1 and CSA Standard C22.2 No. 126.1 CSA...

Materials & Construction Cable tray systems are commonly fabricated from a corrosion-resistant metal or from a metal with a corrosion-resistant nish. The selection of the proper material is essentially an economic consideration. Non-Heat-Treatable Alloys—the initial strength of alloys in this group depends upon the hardening eect of elements such as manganese, silicon, iron and magnesium, singly or in various combinations. The non-heat treatable alloys are designated as 1000, 3000, 4000, and 5000 series. As these alloys are work-hardenable, further strengthening is made possible by various...

Materials & Construction Steel MP Husky oers cable trays and accessories in both the 304 and 316 series. These austenitic alloys are remarkable in several respects. Unlike the other two classes, they contain nickel in quantities from 4 to 22 percent, while the percentage of carbon is kept relatively low. When chromium is increased for improved corrosion resistance, nickel must also be increased to retain the austenitic structure. Steel cable trays are used principally in environments which are relatively free from corrosive attack. They are available with various types of corrosionresistant...

Materials & Construction Fiberglass Typical Applications include: Beer Barrels Chemical Equipment MP Husky’s Fiberglass Cable Tray systems are manufactured from glass ber-reinforced plastic shapes and provides the load capacity of steel, plus the inherent characteristics aorded by our Pultrusion Technology: non-conductive, non-magnetic and corrosion-resistant. Although light in weight, the strength to weight ratio surpasses that of equivalent steel products. MP Husky’s Fiberglass Cable Tray will not rust, nor does it ever require painting. It is available in both polyester and vinylester...
