What is the CP-70K, and which terminals can it crimp?
The CP-70K is a manual hydraulic terminal crimping tool for copper and aluminum terminals. Its crimping range is approximately 4-70 mm², and its maximum output force is 45 kN. The set includes multiple dies and a storage case and is suitable for power and cable installation work.
-
Which crimping dies are included with the CP-70K?
Official information specifies 9 dies covering commonly used sizes from approximately 11 AWG to 2/0 AWG and 4-70 mm². Before crimping, select the correct die from the markings on the terminal and conductor; do not estimate by appearance alone.
-
Can the CP-70K crimp both copper and aluminum terminals?
It can be used with compatible copper and aluminum terminals, but the terminal material, conductor material, and die size must match. Aluminum conductors may also require removal of the oxide layer and application of a suitable contact compound according to the installation standard.
-
What is the basic procedure for crimping a terminal with the CP-70K?
Strip the correct length of insulation, insert the conductor into the terminal, and select the die. Center the terminal in the die and operate the hydraulic handle until crimping is complete. Release the pressure to open the dies, then inspect the crimp impression, conductor insertion depth, and terminal for deformation.
-
How can I tell when a CP-70K crimp is complete?
Operate the tool according to its pressure- or stroke-completion method and confirm that the dies have closed fully; do not judge only by the terminal's appearance. For critical power connections, perform pull-force, dimensional, or resistance checks as required. Do not attempt to repair a poor crimp by applying random additional crimps.
-
Can the CP-70K crimp terminals larger than 70 mm²?
No. Do not exceed the specified range of 4-70 mm². Forcing an oversized terminal can cause an incomplete crimp, die misalignment, or hydraulic-tool overload. Use a tool with greater output force and the correct dies instead.
-
What should I do if the terminal marking does not match the CP-70K die size?
First determine whether the terminal is marked in metric square millimeters, AWG, or another system, then select the die according to the terminal manufacturer's crimping specification. Terminals with different wall thicknesses and constructions may require dedicated dies; conductor cross-sectional area alone is not always sufficient.
-
How can I avoid pinch injuries when operating the CP-70K?
Keep fingers away from the die-closing area, position the terminal before operating the handle, and wear safety glasses and suitable gloves. If the dies become misaligned, the terminal moves, or an abnormal sound occurs during crimping, stop immediately and release the pressure for inspection.
-
How should the CP-70K hydraulic crimper be maintained?
After use, clean the dies and piston area, wipe the tool dry to prevent corrosion, and return it to the case. Prevent dust from entering the hydraulic mechanism. If the tool leaks oil, produces insufficient force, does not retract smoothly, or has damaged dies, stop using it and have it serviced by qualified personnel.
-
How should I choose between the CP-70K and a battery-powered hydraulic crimping tool?
The CP-70K requires no battery and has a simpler construction, making it suitable for intermittent work and small- to medium-size crimps. A battery-powered tool is better for higher volumes, larger conductor sizes, and reducing operator effort. Select according to daily crimp volume, maximum terminal size, and site power conditions.
