Connection fittings are mainly used for connection and repair of wires and lightning conductors of overhead power lines. According to the different structural forms and installation methods, it is divided into three types: compression type, bolt type and pre-twisted wire.

The meanings of the letters and numbers in the product model are:
J-continuation
D-lap
X-Patch
B-Explosion pressure, ditching, repair, lightning protection line
T-oval, jumper
M-busbar
Y-round, pre-twisted wire
S-telescopic, equipment
Numbers indicate suitable wire sizes:
The DC resistance of various connecting fittings is not greater than the DC resistance of the equal-length wire; the current-carrying temperature rise is lower than the temperature rise of the wire. The grip strength of the compression type connecting pipe to the wire shall not be less than 95% of the calculated breaking force of the wire.
