Content Quick Link
Joint-free tight wire (6mm²-35mm²)- solid copper conductors
General features: Safe, stable, no-joint (except the power interface), super-compact, easy to install, economical.
Suitable for single girder overhead crane and other small power cranes. Usually ampacity ≤90 amps, total length≤100m
Detailed information:
- Continuous, joint-free conductors, shipped on a roll. Small space requirements of installation.
- Current collector is made by special materials and it slides smoothly and fast with low noise.
- Bending radius of installation can reach 750mm
- Check more on joint free seamless wire crane power supply line.
Single conductor slide wire (200-2000 amps) - aluminum alloy conductors
- Can be used for most crane needs, high current, long distance power supply preferred.
- Indoor& outdoor
- Convenient maintenance and low maintenance cost.
- High temperature environment can be equipped with heat resistance insulator covering.
- Can provide power input points at any location
