Braid SolutionsFLEXIBLE POWER & GROUNDING
Flexible Grounding and Power OptionsOne of our signature products, BURNDY® Braid Assemblies are an economical and efficient means of protecting electrical equipment from the potentially harmful effects of:
• Shock and vibration
• Terminal or connection area expansion due to temperature changes
• Movement of components
• Misalignment that may occur during the service life of electrical equipment and machinery
• Seasonal movement of outdoor equipment (common in substations)
From shunts and power shunts to grounding jumpers, busbar connections, flexible leads, bonding straps, cable jumpers and flexible gate jumpers—braid assemblies are referred to by many names.
You name it. We can do it. Rely on BURNDY to engineer, manufacture and supply the right configuration for your project.
Customization OptionsWe can help you determine the type of braid that will work best in your situation and then discuss our engineering and manufacturing capabilities to customize your order. Call our Customer Service Representatives and take advantage of our 90 years of experience in the electrical industry.

High Ampacity Requirements
Current Carrying CapacityFlexible copper braid has generally better heat dissipation properties than flat bar, cable or other conductors, and therefore can be expected to have a greater current carrying capacity for given cross-sectional area. This is due to its greater surface area resulting from the woven construction of fine strands. However, ventilation, due to the vertical convection current of air, is appreciably better when the long axis of the braid is vertical rather than horizontal, so that the long sides of the braid, rather than the edges, are exposed to the moving air. This is particularly true when spaced braids are used in multiple as can be seen by comparing Figure 1 and 2.
To take full advantage of ventilation, the cooling convection current of air should be permitted to flow freely between the braids. Therefore, if possible, the braids should be spaced apart, rather than bunched together, as illustrated in Figure 3. The effectiveness of spacing is, of course, greater when the braids are in a vertical position.
Fig. 1
Conventional current have maximum cooling effect with braid in vertical position
Closely bunchedarrangement
OPEN ARRANGEMENTCooling due to convection current much
more effective with spaced braid
Fig. 3
Fig. 2
Ventilation less efficient with braid in horizontal position
Note lack of ventilation here
Bulk Braid
Bulk braid can be ordered with a minimum order quantity of 10 feet. Specify feet in number of inches.
Example: 10 feet of 190 ampere braid is Catalog No. BB077L120.
