| A laminated bus bar is an electronic package made up of thin, flat metal conductors separated and bonded together by a dielectric material and sandwiched between outer insulating covers. Characteristics of the product depend on the elecrical and physical requirements of the specific application. |
| Conductor Size and Material: |
A major factor in determining bus bar conductor size is the system's electrical requirements which include voltage current, temperature rise and voltage drop. Additionally, many bus bars act as structural members. They may contain or act as the interface for circuit components such as IGBTs, capacitors, diodes, fuses etc. CCI can produce bus bars in any size or shape desired.
The selection of conductor material is based on electrical requirements and intended methods of termination. The typical material used in bus bar construction is copper, aluminum or brass. CCI can accommodate customers needs if another material is required. |
| Insulation Material: |
A variety of materials can be used for insulation between conductors and for outer covers. Most commonly used are Mylar (Dupont trademark), epoxy glass, Kapton (Dupont trademark), Nomex (Dupont trademar), epoxy powder coating and tedlar. |
| Edge Sealing |
Depending on the application, exposed conductor edges may be sealed by edge filling or pinch bonding. Edge filling is a process that seals the exposed conductor edges of the bus bar. Tabs, bushings and other electrical interconnects are left exposed. In pinch-bonding, the extended layers of insulation are sealed by "pinching" them together around the bus bar periphery. |
| Connectors and Termination: |
Input and output terminations can take any shape desired. CCI offers both standard and custom connectors and terminations. They can be configured for soldering, mechanical or connectorized methods of attachment. They are usually fabricated from the conductor base as an integral portion of that conductor. Or, they can be attached or inserted directly into the conductor. Our terminations can be designed to accept most wire termination methods. |
| Mounting Holes: |
Insulated mounting holes of almost any size may be incorporated. The number of mounting holes and their placement will depend on the bus bar size and configuration. Enough metal must be left around the conductor holes to satisfy electrical requirements. |
| Electrical Characteristics |
Current carrying capability depends on both resistance and the ability to dissipate heat. |
