Horizontal Elbows
Horizontal elbows are used to make 15 to 90 degree horizontal directional changes in the Superior Cable Bus systems. Horizontal elbows come complete with support blocks, ventilated covers, splice plates, hardware, and fittings. The standard radius of a horizontal elbow is 24 inches, however, custom designed elbows are available to suit the bending radii and directional requirements for a specific installation.
Vertical Elbows
Vertical elbows are similar to horizontal elbows but are used to make changes in the vertical direction of the Superior Bus system from 15 to 90 degrees. Unlike horizontal elbows, these fittings come in two (2) types; the inside vertical elbow to change the upward direction and conversely the outside vertical elbow to change the direction downward.
Environmental Seals
An environmental seal is used when a Superior Bus passes through a wall, roof or any structure requiring isolation from environmental elements such as water, air, gas, etc. In order to provide a watertight connection a sealant compound is applied to every point of contact between the cable bus/cables to the environmental flange plate and supporting structure.
Tap Boxes
A tap box is used when it is necessary to "tap-off" a portion of current flow from the main Superior Bus run to an intermediary load. Tap boxes consist of a aluminum or steel housing complete with bus bars and insulators. Superior tap boxes are suitable for both indoor and outdoor use and are available with CSA 3 weather resistant rating.
Equipment Box
An equipment box is used when Superior Bus has to terminate power cables at outdoor electrical equipment such as transformers or motors. The equipment box provides the work space to facilitate the separation of phases and cable terminations. Standard outdoor equipment/termination boxes are made of aluminum, provide grounding to equipment enclosures, and are water-tight with CSA 3 rating.
Multi Cable Transit or MCT Firestop
The MCT Fire Stop provides a fireproof seal rated for up to 4 hours, for use when cable tray passes through a wall, floor, deck, bulkhead, etc. Constructed from a neoprene based product that forms a complete seal, the MCT is suitable for unstable and hazardous locations, being both air and water tight, even under high shock or high vibration conditions. While maintaining dielectric strength, the MCT is compact and can accommodate a large variety of power cables, as well as other conduits, piping and tubing.
Environmental Seal and Firestop Pillow Combination
This environmental seal combined with mineral fiber fire stop pillows is suitable for applications where a Superior Bus or cable tray penetrates a wall or opening that is required to be fire rated. The pillows are tightly packed and inserted lengthwise into openings between conductors and when is exposed to fire, the pillows rapidly expand to lock the seal in place.
Compression Lugs
Two hole long barrel compression lugs that are UL listed and CSA Certified are supplied for the power cables. They are CSA Certified to 35 KV e protected from environmental elements such as water, air, etc. applicable for low voltage and high voltage of up to 35 KV. The compression terminal lugs are temperature rated to a minimum of 90° C and are tin-plated to inhibit corrosion. Compression terminal lugs are suitable for stranded copper conductor and have completely closed transitions to protect the end of the power cable from environmental hazards.
Cable Terminations
The power cables are supplied with heat or cold shrink termination kits.
Cold shrink termination kits are used for 5KV, 15KV and for higher voltage applications.
The outdoor termination kit (with sheds) and indoor termination kit (without sheds) are medium
voltage cold shrink polymer terminations that are designed for fast, easy and reliable
installation. No heat or complicated assembly is required. The termination shrinks evenly
as the inner support core is removed creating a tight void free interface between the termination
and the power cable. The installed termination kit also provides a superior moisture seal to the power cable.
Heat shrink termination materials are used for 600 volts systems.
The heat shrinkable cable sleeves provide reliable performance for terminations
as well as mechanical and environmental protection. They are highly split resistant
and fast shrinking for ease in installation.
Support Frame
The Superior Cable Bus systems are supported according to NEMA standards and supports are installed up to 20 ft on center. Cable bus can be supplied with a variety of structural and trapeze supports, including T-type, frame support, pedestal support and wall support. This support frame is connected to the support structure and holds the load of the total cable bus system with the help of the support structure.
Support Frame
The support structure is the main support system which will carry the load of the whole Superior Cable Bus through the support frame. This support structure can be the main structure of the project which can support not only cable bus system but also other systems installed in the project. With our advanced manufacturing facility and experienced engineering and design team, we build a cost effective, reliable and safe support structure that can be used for the Superior Bus system as well as for other systems. We also design and manufacture any custom support system that is required for a specific installation.
