JMK high-voltage cable processing machines are designed for cutting, stripping and heavy-duty terminal crimping of large cross-section cables used in electric vehicles, energy storage systems, charging equipment, photovoltaic systems and industrial power applications.
Our product range includes large cable cutting and stripping machines, pneumatic-hydraulic crimping machines, intelligent servo crimping machines, automatic double-end crimping equipment and complete high-voltage wire harness production lines. Available crimping forces range from 6T to 50T, with selected systems supporting cables up to 300 mm².
High-voltage cables are thicker, heavier and less flexible than conventional low-voltage wires. Their larger conductor cross-sections and insulation layers require suitable feeding, cutting, stripping and crimping equipment.
Our high-voltage cable processing machines can be configured for the following processes:
Large cable feeding
Fixed-length cable cutting
Outer insulation stripping
Single-end or double-end stripping
Heavy-duty terminal crimping
Single-end or double-end terminal processing
Number tube insertion
Heat-shrink tube positioning
Heat-shrink tube processing
Cable and terminal presence detection
Optional CCD visual inspection
Optional crimp force monitoring
The exact processing sequence depends on the cable construction, conductor cross-section, terminal type and finished harness requirements.
Accurate cutting and stripping are the foundation of high-voltage cable assembly. Excessive stripping force can damage conductor strands, while incomplete stripping can interfere with terminal insertion and crimping.
The JM-70 large square cutting and stripping machine is designed for large cross-section cable preparation. It provides a dedicated solution for manufacturers that need repeatable cable length and stripping control before terminal crimping.
Our cable cutting and stripping machines can be used as independent processing equipment or as part of a full automatic cable processing machine.
When selecting a cable processing machine for cable cutting or stripping, the following factors should be confirmed:
Cable outer diameter
Conductor cross-section
Insulation material
Required cutting length
Full-strip or half-strip requirements
Stripping length and tolerance
Conductor strand protection
Target production capacity
Large copper cables and high-current terminals require greater crimping force than conventional signal-wire terminals. JMK provides pneumatic-hydraulic and servo-driven cable processing machines for terminal crimping.
The 6T/10T/20T/30T pneumatic-hydraulic terminal crimping machines support different cable and terminal ranges, with individual models selected according to the required crimping force.
The 20T/30T/50T intelligent servo crimping machines are designed for large new energy cables and support conductor cross-sections from 2.5 mm² to 300 mm², depending on the selected model.
Available terminal crimping configurations include:
6T, 10T, 20T, 30T and 50T crimping force
Pneumatic-hydraulic crimping
Servo-controlled crimping
Adjustable crimping force and height
Interchangeable crimping dies
Barcode scanning on selected models
Optional MES connectivity
Customized dies for non-standard terminals
The required crimping force should be confirmed through the cable, terminal and crimp profile rather than selecting equipment based only on conductor size.
For repetitive harnesses requiring terminals on both cable ends, an automatic double-end crimping system can reduce transfers between cutting, stripping and crimping workstations.
The JMK-701 large square cable bare-terminal automatic double-end crimping machine combines large cable preparation with double-end terminal processing. It is suitable for applications where both cable ends follow a repeatable cutting, stripping and crimping sequence.
An automatic double-end cable processing machine can help reduce:
Manual cable measurement
Repeated material handling
Separate stripping operations
Terminal positioning variation
Work-in-process inventory
Dependence on multiple independent machines
Actual applicability depends on cable flexibility, cutting length, terminal geometry and required production cycle.
The JM-700 high-voltage wire harness production line is a full automatic cable processing machine developed for large high-voltage cables.
Its production process can include:
Cable feeding
Number tube or heat-shrink tube preparation
Outer insulation stripping
Terminal crimping
Heat-shrink tube positioning
Heat-shrink processing
Finished harness collection
The JM-700 supports cable cross-sections from 2.5 mm² to 300 mm², subject to customization. Its crimping system can be configured from 6T to 50T according to the cable and terminal requirements.
The line can also be equipped with wire detection, crimping error detection, optional CCD visual inspection and optional crimp force monitoring.
High-voltage cable assemblies are widely used in equipment that transfers large electrical currents. The appropriate processing method depends on the cable structure, terminal type, voltage class and environmental protection requirements.
Typical applications include:
Electric vehicle power cables
New energy vehicle wiring harnesses
Battery and energy storage connections
EV charging equipment
Photovoltaic cable assemblies
Rail transit electrical systems
Industrial power distribution
Heavy-duty electrical cabinets
A new energy automotive wire harness machine may require high-force crimping, large cable feeding and heat-shrink processing within the same line. Other projects may require separate cutting, stripping and crimping machines for more flexible batch production.
A high-voltage terminal connection must meet the required mechanical and electrical acceptance criteria. The machine provides process control, but the final crimp specification must be determined from the cable, terminal and application requirements.
Selected equipment can be configured with:
Crimp force monitoring
CCD visual inspection
Cable presence detection
Terminal presence detection
Crimping error alarms
Barcode scanners
MES connectivity
Production parameter storage
Defective-product separation
Crimp force monitoring helps identify changes in the crimping process. CCD inspection can check selected visible characteristics when the defect can be reliably detected through machine vision.
Pull-force testing, cross-section analysis, electrical testing and insulation testing should be defined separately according to the customer’s quality-control plan. They should not be assumed to be standard functions of every machine.
High-voltage cable terminals are available in different shapes and conductor ranges. JMK crimping machines can support multiple die profiles, including:
Hexagonal crimping dies
Open hexagonal dies
Quadrilateral dies
Four-point indenting dies
Upper and lower stamping dies
Customized dies for special terminals
Quick die changes help manufacturers process multiple terminal specifications without dedicating one machine to each terminal type. The cable, terminal and die combination should still be validated through sample crimping before production.
Before selecting equipment, please provide:
Cable construction and application
Conductor material
Cable cross-section
Cable outer diameter
Insulation material
Required cutting length
Stripping length and tolerance
Terminal drawing and samples
Required crimp profile
Pull-force requirement
Heat-shrink tube or number tube requirements
Target production capacity
Inspection and data requirements
Based on this information, we can recommend an independent cable cutting and stripping machine, a heavy-duty terminal press, an automatic double-end crimping machine or a complete automotive wire harness machine production line.
