定义
A specialized mounting bracket designed with integrated insulating properties to securely fasten power distribution busbars while maintaining electrical isolation from grounded structures. This component serves dual functions: mechanical support to prevent vibration-induced fatigue and electrical insulation to prevent short circuits and ground faults. It typically consists of a metallic bracket for structural integrity coated or combined with dielectric materials like epoxy resin, ceramic, or high-grade polymers to achieve required insulation resistance and dielectric strength.
工作原理
The mounting bracket/insulator operates on the principle of mechanical fixation combined with dielectric separation. The metallic bracket provides structural rigidity and secure attachment points to the supporting framework, while the insulating layer or integrated insulator creates a high-resistance barrier between the conductive busbar and grounded surfaces. This prevents electrical current leakage, reduces electromagnetic interference, and maintains safe clearance distances as per electrical safety standards. The design often incorporates thermal expansion compensation to accommodate temperature variations in high-current applications.
材料
Bracket: Galvanized steel (ASTM A653)stainless steel (AISI 304/316)or aluminum alloy (6061-T6). Insulator: Epoxy resin (glass-filled for strength)ceramic (alumina or porcelain)or engineered polymers (PTFEPEEKor polycarbonate with flame-retardant additives). Fasteners: Stainless steel (A2/A4 grade) with insulating washers.
