TYPE YS-AT
HIGH VOLTAGE
UNINSULATED ALUMINUM
COMPRESSION SPLICE
Type YS-AT is a high-conductivity aluminum
electro-tin plated compression butt splice
with tapered ends for high voltage applica-
tions up to 35 kV.
The YS-AT provides the same benefits as the
YS-A with the addition of tapered ends for
easy installation of high voltage insulating
kits. Tapered ends aid in preventing corona
emission and insulation breakdown.
Recommended for high voltage splice
applications.
Features and Benefits
• Tapered ends for applications
through 35kV.
Permits easy taping and aids in
preventing corona emission and
insulation breakdown.
• Heavy wall aluminum tubing.
For use with combinations of AL-AL,
AL-CU, CU-CU
