Flat Reeling Cables

Flat reeling cables are indeed an excellent choice for reeling systems, offering a unique combination of flexibility, durability, and space efficiency. Their design makes them particularly well-suited for industrial applications where space constraints, frequent movement, and harsh environmental conditions are common. Below is a detailed exploration of Flat Cables, focusing on their roles, structure, technical specifications, and advantages in reeling systems, with a specific example from LSTKABEL.

 

1. Roles of Flat Cables in Reeling Systems

 

Flat cables are designed with a rectangular cross-section, which provides several advantages over traditional round cables:

Flexibility and Durability:

The flat design allows for easier bending and greater flexibility, making them ideal for applications requiring constant movement, such as reeling systems.

Their durability ensures a longer lifespan and reduces the risk of system damage, promoting reliable long-term operation.

Space-Saving Design:

Flat cables can be installed in tight spaces, such as narrow trenches, pipes, or intricate mechanical systems, optimizing space utilization.

The flat structure also enables a tidier and more organized cable layout, reducing clutter.

High Conductor Density:

Flat cables can accommodate more conductors in a compact structure, allowing for the transmission of multiple signals simultaneously.

This is particularly beneficial in reeling systems where multiple connections are required over long distances.

 

2. LSTKABEL’s Flat Cable

 

LSTKABEL offers a high-quality flat cable designed specifically for reeling systems, such as crane installations, floor conveyor systems, and shelf control units. This cable is known for its excellent flexibility, space-saving design, and reliable signal transmission.

2.1. Structure of Flat Cable

Outer Sheath:

Made from a specialized TM2-type PVC compound, the outer sheath is black and provides excellent protection against mechanical stress, oils, chemicals, and radiation.

Conductor:

The conductor is made of bare copper, complying with the DIN VDE 0295 Class 5 standard, ensuring high flexibility and durability.

Insulation:

The conductor insulation is made from a TI2-type PVC compound, which offers additional protection and flexibility.

Core Arrangement:

The cable is available with 4 to 20 cores, and cross-sections range from 0.75 mm² to 70 mm².

Unlike round cables, the cores in flat cables are arranged parallel to each other in a defined sequence, which enhances flexibility and reduces stress during bending.

For cables with 5 cores or fewer, each core is color-coded for easy identification.

For cables with 7 cores or more, core numbers are printed continuously in white on the black insulation.

Protective Conductor:

A distinctive feature is the inclusion of a green-yellow protective conductor, which enhances electrical safety during operation.

2.2. Technical Specifications and Properties

Standards Compliance:

The cable complies with EN 50214 and DIN VDE 0283-2 standards, ensuring high-quality performance.

Temperature Range:

For flexing applications: -5°C to +70°C.

For fixed installations: -40°C to +80°C.

Nominal Voltage:

For cross-sections of 0.75 mm² and 1 mm²: U0/U 300/500 V.

For cross-sections of 1.5 mm² or more: U0/U 450/750 V.

Bending Radius:

The cable has an extremely small bending radius, making it highly flexible and suitable for reeling systems.

The minimum bending radius is 10 times the cable’s outer diameter, which reduces wasted space and allows for efficient installation.

Mechanical Stress Resistance:

The cable is designed to withstand continuous winding and unwinding, preventing twisting or tangling during operation.

Packeting Possibility:

The cable supports efficient and reliable data packet transmission, ensuring data integrity and minimizing latency.

Environmental Resistance:

Resistant to oils, chemicals, and radiation (up to 80 Mrad), making it suitable for harsh industrial environments.

The PVC material is self-extinguishing and flame-retardant, complying with VDE, EN, and IEC standards, which reduces risks in case of fire or explosion.

 

3. Advantages of LSTKABEL’s Flat Cable

 

High Flexibility:

Ideal for dynamic applications like reeling systems, where frequent bending and movement are required.

Space Efficiency:

The flat design allows for easy installation in tight spaces and reduces clutter.

Durability:

 

Resistant to mechanical stress, oils, chemicals, and radiation, ensuring long-term performance in harsh environments.

Safety:

The inclusion of a green-yellow protective conductor and flame-retardant properties enhances electrical safety.

Efficient Signal Transmission:

Supports multiple conductors in a compact structure, enabling reliable transmission of power and signals.

 

4. Installation Guidelines

 

To ensure safe and effective operation, the installation of flat cables must follow specific guidelines:

Cable Placement:

Properly align the cable to avoid excessive bending or twisting.

Trolley Placement:

Ensure trolleys are correctly positioned on guiding rails or carrier beams.

Environmental Considerations:

Avoid exposure to extreme temperatures or corrosive substances beyond the cable’s specified limits.
