Busbar supports are structural components used to securely mount and hold busbars in electrical distribution systems. Busbars act as conduits for electricity in panelboards, switchgear, motor control centers and other power applications. Busbar supports provide a safe and organized way to route and distribute power through busbar networks. They prevent short circuits, damage from vibrations, and other electrical hazards.
Common standards for busbar supports include IEC 61439, DIN 43871, and UL 857. They are designed to withstand high currents up to 630A and work safely in both indoor and outdoor settings. Busbar support systems play a critical role in safe and reliable electrical power distribution in industries, utilities, buildings and infrastructure.
Choosing the right busbar supports involves factors like:
Proper design ensures supports can handle mechanical and electrical stresses for the application.
GRL offers various busbar support products:
Copper, aluminum and insulating materials are used to manufacture supports up to 630A ratings.
Installing busbar supports involves:
Proper installation ensures the supports do their job safely.
GRL busbar supports offer advantages like:
What are busbar supports used for?
Busbar supports are used to securely mount and hold busbars in electrical switchgear, panelboards, busway systems and other distribution equipment. They provide organized routing and prevent damage from vibration, short circuits and more.
What materials are busbar supports made from?
Common materials are copper or aluminum for conducting busbars and insulating polymers or ceramics for insulated supports. Stainless steel is also used for brackets and hardware.
What are the different types of busbar supports?
Major types are clamp style, wall-mounted brackets, suspended hangers, and hardware components like bolts, nuts and washers.
How are busbar supports installed?
Busbar supports are installed by mounting to the enclosure, then attaching busbars using bolt holes. Proper grounding, bonding and spacing should be checked.
How much weight can busbar supports hold?
This depends on the style and size of support. Typical capacities range from around 50 lbs for small supports up to hundreds of pounds for larger sizes.
How far apart should busbar supports be spaced?
Spacing between supports depends on the length and weight of the busbar. A general guideline is to place supports every 1-3 feet or as recommended by manufacturer.
How do I choose the right busbar support size?
The support size should match the busbar dimensions and amperage rating. Consider the cross-sectional size of busbars and number being held.
What standards apply to busbar supports?
Major standards include IEC 61439, DIN 43871 and UL 857. They cover strength, spacing, insulation, grounding and other design factors.
Can busbar supports be used outdoors?
Yes, outdoor busbar supports are available with UV stabilization, weatherproofing and corrosion resistance. Proper enclosure also helps.
How do I ground busbar supports?
For metal supports, a grounding bolt, lug or clip is used to connect the support to the overall grounding system. Insulated supports may not need grounding.
What size bolt is used for busbar supports?
M6 and M8 bolts are common sizes. Stainless steel hardware is recommended for corrosion resistance. Bolt size depends on current rating.
What is the maximum current for busbar supports?
Busbar supports are available for up to 630A applications, with higher capacities possible. The current rating depends on busbar size and support design.
How do I connect busbars to supports?
Busbars are attached to supports using bolt holes in the support base. Ring tongue terminals, cable lugs or busbar tabs help terminate connections.
What is the difference between busbar holders and busbar supports?
Supports provide fixed mounting while holders allow removable installation. Both securely hold and position busbars.
How much do busbar support systems cost?
Pricing can range from $50 up to several hundred dollars depending on quantity, size, material and design. GRL supports offer cost savings vs. European/US brands.
Where can I buy busbar supports?
GRL sells busbar supports directly and through electrical equipment distributors globally. Custom designs are also available.
Do busbar supports require maintenance?
Occasional inspection of connections and hardware for tightness is recommended. Proper installation ensures low maintenance.
How long do busbar supports last?
With quality materials and proper installation, supports typically last 10-15 years or more before replacement is needed.
How do I design a busbar support system?
Consider busbar size, number, and weight load along with required spacing and positioning. Consult manufacturers for design guidance.
How are busbar supports different from cable trays?
Supports hold rigid busbars rather than cables. They feature insulators and attachment points to mount busbars securely.
