TE's ASBS is a range-taking mechanical shear bolt connector for #2 AWG compact through 1000 kcmil concentric conductors. It joins aluminum to aluminum, aluminum to copper, or copper to copper, and it is built mainly for underground splicing up to 35 kV. No crimp tool or dies are needed. You tighten the bolts with a ratchet wrench until the heads shear off.

| Feature | What it means |
|---|---|
| Range-taking body | One connector covers several conductor sizes, which cuts inventory and helps avoid the wrong connector |
| Tin-plated aluminum alloy body | Dual rated for aluminum and copper conductors |
| Shear bolts | Each bolt breaks off at a set torque, so the contact force is right without a torque wrench |
| Solid center stop | Positions the conductors and prevents oil leakage when splicing oil-impregnated conductors |
| Tooling | Standard ratchet wrench with the right hex sockets; TE recommends the IT-1000-019 holding tool to keep the conductor core from bending |
| Fit | Pre-engineered to fit medium voltage cable accessories up to 35 kV |
The ASBT is the terminal version. TE says it is a range-taking mechanical connector for power cable terminations, underground and above ground, at voltages up to 69 kV. Three connector sizes cover #2 AWG compact to 1250 kcmil concentric Class B stranded. It is dual rated for aluminum and copper conductors, mounts to flat bar or equipment pads with 2-hole NEMA spacing, and needs no crimp tools or dies. The shear bolt heads are part of the terminal, so each bolt gets the right torque. A standard ratchet wrench with the right socket installs it. TE recommends a holding tool (IT-1000-019) to avoid bending the conductor core.
