2.5-4-6mm2 AWG14-10 Crimping Tool Hand Tool Crimping Pliers Crimp Tools
Professional-grade photovoltaic crimping pliers that are labor-saving, durable, and accurate in crimping, especially suitable for installers or teams that need to crimp for long periods of time.
Core advantages:
1. Save 35% or more effort
The newly designed lever structure requires 35% less force to crimp wires of the same thickness compared to ordinary pliers.
2. Stable crimping quality
Equipped with a precise locking device, the crimping effect remains the same after 100 crimps as it does on the first crimp, and it won't become looser with use.
3. Super durable
All key components are thickened and reinforced, ensuring a normal service life of 3 to 5 years.
4. Comfortable to use
The handle is optimized according to the human hand grip posture, with balanced center of gravity and adjustable crimping angle.

Q1:Are you a trading company or a manufacturer?
We are Integration of industry and trade, our company has a history of 40 years. We have been specializing in the production of a series of photovoltaic electrical products, such as circuit breaker, pv combiner boxes, pv connector, surge protector, pv fuses, pv tool accessories and etc.
Q2:If OEM is acceptable?
We can provide OEM and ODM services. We have many different specifications and appearances for customers to choose.
Q3:Do you provide sample? Free or charge?
We can provide free samples to customers, but only one piece, but customers need to bear the freight. For some special products, we also offer free samples. Considering their particularity, we usually refund the sample fees to customers after they place formal orders.
Q4:How long is your delivery time?
Our delivery time is determined according to the purchase quantity. Generally, it is about 3-40 days, less than 300 pieces within 5 days, 300-2000 pieces within 7-15 days, 2000-20000 only within 15-40 days.
Q5:What is a photovoltaic crimping pliers?
It is a specialized tool for crimping cables in photovoltaic systems. It uses mechanical force to press the metal terminal and the cable core into a low-resistance and high-strength electrical connection, ensuring stable current transmission between photovoltaic modules.
Q6:What are the differences between a photovoltaic crimping pliers and a regular one?
Firstly, the material of the photovoltaic crimping pliers needs to be UV-resistant and corrosion-resistant (such as chrome-plated or alloy steel). Secondly, the product precision should match the dedicated molds for photovoltaic cables (such as 4mm²/6mm²).
Q7:How to choose a suitable photovoltaic crimping pliers?
The wire diameter range should be 4-10mm² (matching the specifications of photovoltaic cables); the crimping molds should be compatible with mainstream terminals such as MC4 and H4; the operation method can be manual (with a force-saving lever design) or hydraulic (suitable for larger wire diameters).
Q8:What to do if the terminal becomes loose after crimping?
Possible reasons: the molds are not aligned, requiring replacement with matching molds; insufficient pressure, requiring inspection of the pliers for damage or selection of a higher-pressure model; terminal deformation, requiring replacement with original factory terminals (avoiding inferior copper-aluminum mixed materials).
Q9:Can it crimp aluminum cables?
Not recommended. Photovoltaic systems usually require copper cables (low resistance, anti-oxidation), and aluminum cables need dedicated crimping tools and anti-corrosion treatment.
Q10:How to maintain it daily?
After each use, remove metal debris (to prevent mold jamming); apply silicone-based grease to the rotating shaft monthly; store in a dry environment to prevent mold rusting.
Q11:What to do in case of a loose crimp?
Use wire strippers to remove the old terminal and crimp a new one; apply conductive paste and reinforce with heat shrink tubing (only for emergency, replacement should be done as soon as possible).
Q12:What safety precautions should be taken during operation?
Confirm that the system is completely powered off before crimping (to prevent DC arc); wear insulating gloves and safety glasses (to prevent metal splashing); do not exceed the specified wire diameter range (which may cause the pliers' jaws to crack).
Q13:Can photovoltaic crimping pliers be used in energy storage systems?
Yes, but it is necessary to confirm: voltage level matching (the voltage of energy storage batteries may be higher than that of photovoltaic strings); consistent terminal types (such as some energy storage systems using OT terminals).
