| | | Precision Dies form a Solid Homogenous Mass... | | |
| | | |
| | | The T&B method utilizing compression tools with matching dies forms the connector and conductor into a solid, homogenous mass to provide an optimum electrical bond between connector and conductor. Thomas & Betts method dies are designed to produce a circumferential, hex- or diamond-shaped compression rather than a simple indent. Precision dies are an integral part of the Thomas & Betts method. The precision hardened steel dies exert tremendous, controlled pressure on the connector and conductor. The dies compress the connector around the cable, converting the round strands to hexagonal or diamond shapes and forming the strands and connector into a solid mass. Each die is designed so that all conductors receive the same amount of compression force. The circumferential compression creates a large area of high pressure contact between cable and connector which, in turn, assures high conductivity, low resistance, and high pullout values which exceed UL requirements. These features result in a permanent, low installed cost connection. You can install it, and forget it. | | |

| | | Thomas & Betts' System Tells You Where to Place the Installing Die. | | |
| | | |
| | | Color-Keyed® connectors not only identify the correct installing die to be used for positive compressions, but also indicate the proper placement of the die on the connector. This is done by the bands of color on the connector which match the color on the dies. Compression is made between or on these color bands. The color name is also spelled on the connector as an added means of identification. | | |
| | | |
| | | Before compression, a typical cross section of cable and connector consists of about 75% metal and 25% air. | | |
| | | After air compression by the T&B Method, the cross section looks like this, 100% metal with virtually no air spaces. | | |

| | | Thomas & Betts Dies Offer Inspection Capability. | | |
| | | |
| | | Copper Die located BETWEEN bands | | |
| | | Aluminum Die located ON Bands | | |
| | | Dies that are used in Thomas & Betts hand and hydraulic tools contain the "die code" numbers which are engraved on the compression surface of the die. Under compression, this number becomes embossed on the completed connection for inspection purposes. The inspector compares the die code number embossed on the connector with the die table to ensure that the proper connector was compressed with the correct die for that particular size conductor. | | |
