Type PROTOLON (SMK) (N)TSCGEWOEU Reeling Cable

In heavy-duty industrial environments, such as those involving fast-moving container cranes and large mobile equipment, reliability is crucial. One of the key elements that keeps operations running smoothly is having the right cable for the job.

That's why the Type PROTOLON (SMK) (N)TSCGEWOEU Reeling Cable is an ideal choice for applications under high mechanical stresses. This cable is designed to handle everything from high travel speeds and dynamic tensile loads to frequent torsional stresses—making it perfect for fast-moving, high-performance equipment.

This high flexibility design ensures that the cable can withstand multiple changes of direction, while its rugged PROTOFIRM outer sheath provides enhanced protection against the mechanical strains that occur during reeling operations.

Available in multiple voltage levels—1.8/3 KV, 3.6/6 KV, 6/10 KV, 8.7/15 KV, and 12/20 KV—this cable is versatile and reliable for a variety of heavy-duty industrial applications.

What Does Type PROTOLON (SMK) (N)TSCGEWOEU Stand For?

Each part of the Type PROTOLON (SMK) (N)TSCGEWOEU Reeling Cable name reflects key characteristics and technical standards.

Understanding the meaning behind each letter helps illustrate just how robust and specialized this cable is:

PROTOLON (SMK):

Refers to the high-grade PROTOLON material used in the insulation and sheath, giving the cable superior electrical and mechanical performance. The "SMK" highlights that this is a specialised variant tailored for high-demand industrial environments.

(N)TSCGEWOEU:

This string of letters reflects German industrial cable standards, primarily based on DIN VDE 0250-813. Each letter signals specific features like:

(N): Compliant with VDE standard cables.

TSCGE: Indicates the cable is designed for tensile strength, torsion resistance, and high mechanical durability.

WOEU: This section denotes the outer sheath material—designed for abrasion resistance, enhanced durability, and outdoor/indoor usage.

This cable is engineered to exceed expectations in terms of both flexibility and strength, making it highly suitable for demanding environments like container terminals and other industrial sites with fast-moving equipment.

Key Features of the PROTOLON (SMK) Reeling Cable

High Flexibility Design

One of the standout features of the PROTOLON (SMK) Reeling Cable is its high flexibility. This allows the cable to endure rapid movements, changes in direction, and torsional stresses without wearing down prematurely. This flexibility is essential for applications where equipment needs to move quickly and frequently.

Advanced Sheath Technology

The PROTOFIRM outer sheath of the cable is where the durability comes into play. This sheath is made of high-grade rubber compounds based on PCP (polychloroprene), ensuring high resistance to abrasion and tearing. The bright red colour not only makes it highly visible in industrial settings but also serves as a warning for workers around heavy machinery.

This abrasion-resistant sheath is critical in environments with high mechanical stresses, offering additional protection and extending the lifespan of the cable.

The inner sheath features a sandwich double-layer design using a special compound based on EPR (ethylene propylene rubber), which also acts as a water barrier.

This design provides an extra layer of protection, helping to keep the cable operational in harsh conditions, including those involving moisture or water exposure.

Superior Conductor Design

The cable’s conductor and earth conductor are made from tinned electrolytic copper, finely stranded to Class FS standards. This ensures excellent conductivity and helps the cable resist mechanical strain without compromising performance.

The PROTOLON HS insulation—based on a high-quality compound of EPR—improves the cable’s mechanical and electrical properties, ensuring it can safely carry higher electrical loads even in extreme conditions.

Electrical Parameters and Voltage Levels

Designed to support multiple voltage levels, the PROTOLON (SMK) Reeling Cable is available for the following voltage classes: 1.8/3 KV, 3.6/6 KV, 6/10 KV, 8.7/15 KV, and 12/20 KV. This versatility allows it to be used in a wide range of applications, from standard reeling operations to high-performance, high-voltage scenarios.

The cable also features advanced electrical field control with an inner semiconductive layer of EPR and an outer semiconductive layer of modified NBR. This "easy strip" design makes the cable easier to work with during installation and maintenance.

Designed for Harsh Conditions

The PROTOLON (SMK) cable is built to withstand harsh industrial conditions, making it ideal for mobile equipment like container cranes, gantry cranes, and other fast-moving machinery. It is highly resistant to a wide range of environmental factors, including:

Oil Resistance: In line with DIN EN 60811-404 and DIN VDE 0473-811-404 standards.

Weather Resistance: Unrestricted use outdoors and indoors, with excellent resistance to ozone, UV, and moisture.

Water Resistance: Suitable for wet environments as per HD 2216 guidelines.

Whether exposed to oil, high humidity, or outdoor elements, this cable performs consistently and reliably, which is critical in industrial settings where downtime can be costly.

Thermal and Mechanical Performance

In terms of temperature handling, the cable can function in environments with temperatures ranging from -50°C to +80°C for fixed installations, and -35°C to +80°C in fully flexible operations. The max operating temperature of the conductor reaches 90°C, while the max short-circuit temperature goes up to 250°C.

In addition to its impressive temperature tolerance, the PROTOLON (SMK) cable can handle a tensile load of up to 20 N/mm² during regular operation and up to 30 N/mm² during acceleration. The cable’s torsion protection is reinforced with a polyester braid, which enhances the overall durability of the sheath system and helps prevent twisting damage.

For applications requiring directional changes, the cable has a minimum bending radius in line with DIN VDE 0298 part 3. It’s also been tested for reversed bending and torsional stress, ensuring it can handle the rigorous demands of modern industrial applications.

Applications and Compatibility

The Type PROTOLON (SMK) Reeling Cable is ideal for use in various industrial applications, especially in scenarios where high mechanical stresses are present. Its primary applications include:

Gantry cranes in port and industrial settings.

Reeling operations that require high-speed cable movement.

Container terminals and fast-moving equipment in logistics and warehousing.

Heavy-duty mobile equipment that faces extreme operational demands.

The cable’s durability and high mechanical flexibility make it suitable for both standard industrial applications and more demanding tasks where frequent changes in direction, speed, or torsional stress are common.
