Thermally efficient power busway system with integral clamping mechanism

An electric power busway system comprising:

• a plurality of electric power bus bars;
• an elongated housing section comprising a pair of opposite rail supports and a pair of longitudinally extending opposing plates, said plates being shaped with a plurality of troughs, each trough cooperating with one opposing said trough and receiving one said bus bars, said trough in said housing section supporting and retaining said bus bars at proper intervals from each other;
• and
• a projection extending linearly from said plates and receiving a complementary locking groove extending linearly from said rail supports for interlocking said rail support and said plates together where said rail supports come in contact with said plates.

An electric power busway system comprising:

• a plurality of electric power bus bars;
• a housing section of a multi-piece metallic construction having a least two separate pieces;
• and
• joints for fastening pieces of said housing section together where the separate pieces of said housing section are in contact together, said joints having a top surface and a bottom surface being formed using a punch and die tool set, wherein the top surface of the joints are deformly melded into the bottom surface, with no through-hole created in the surfaces of the joints.

An electric power busway system comprising:

• a plurality of electric power bus bars;
• an elongated housing section of a multi-piece metallic construction;
• a plurality of troughs on said housing section, each trough cooperating with one opposing said trough to support one of said bus bars, keeping said bus bars at proper intervals from each other;
• a fastening member for fastening the pieces of said housing section together where said pieces come in contact;
• and
• at least one layer of an insulative protection sleeve covering at least two of said electric power busbars, said sleeve being sandwiched between said bus bars and said housing section primarily where said bus bars come into contact with said housing section, said protection sleeve being made out of a one-piece construction.

An electric power busway system comprising:

• a plurality of electric power bus bars;
• an elongated housing section of a multi-piece metallic construction;
• troughs on said housing section to support said bus bars, keeping said bars at proper intervals from each other;
• and
• at least one pair of opposing first and second clamping blocks and a fastener extending through said opposing first clamping block, said housing section and said opposing second clamping block, said fastener directly clamping and applying friction on said housing section to keep said bus bars from sliding out of said housing section.
