TYPE YRB-U
HYREDUCER™ SPLICE
FOR ALUMINUM-TO-ALUMINUM
AND ALUMINUM-TO-COPPER
Type YRB-U splice is designed for use within
underground systems. Aluminum splices are
tin-plated and recommended for use on
Aluminum-to-Aluminum and Aluminum-to-
Copper cables. All splices have solid center
stop for use with oil filled and non-oil filled
cables. The Outside Diameter is held
constant to minimize installation dies and
connectors are prefilled with PENETROX™.
Rated up to 35 kV.
