Understanding the PROTOLON(FL) (N)TSFLCGEWOEU Cable
The PROTOLON(FL) (N)TSFLCGEWOEU is a medium voltage flat reeling cable engineered for environments where cables face continuous movement, high tensile loads, and harsh weather conditions. Unlike traditional round cables, its flat design allows it to lie flat during installation, making it ideal for space-constrained applications and systems requiring repeated reeling, such as container cranes, excavators, and large mobile equipment.
The cable’s nomenclature—(N)TSFLCGEWOEU—reveals its specialized design:
(N): Conforms to DIN VDE 0250-813, a German standard ensuring high-quality cable construction.
T: Indicates suitability for reeling operations, capable of enduring constant movement.
SFL: Denotes a flat cable optimized for tight spaces and heavy mechanical use.
CGE: Refers to tinned electrolytic copper conductors and high-quality Ethylene Propylene Rubber (EPR) insulation, enhancing flexibility and strength.
WOEU: Signifies weather resistance, UV protection, and suitability for indoor and outdoor use.
This combination of features ensures the cable’s resilience in dynamic, high-stress environments, making it a standout choice for industrial applications.
Applications: Powering Heavy-Duty Industrial Systems
The PROTOLON(FL) cable is tailored for mobile equipment subjected to high mechanical stresses. Its primary applications include:
Cranes: Ideal for fast-moving container cranes and gantry systems, where constant reeling and directional changes are common.
Hoists and Conveyors: Supports reliable power transmission in systems requiring flexibility and durability.
Excavators and Mining Equipment: Withstands the harsh conditions of mining operations, including exposure to dust, moisture, and mechanical stress.
In South Africa, where mining and port operations are critical to the economy, the PROTOLON(FL) cable is particularly relevant. The country’s mining sector, a cornerstone of its GDP, relies on robust equipment to extract minerals like gold, platinum, and coal. Similarly, ports such as Durban and Cape Town handle significant container traffic, necessitating reliable crane systems powered by durable cables like the PROTOLON(FL).
Comparing PROTOLON(FL) to PROTOLON (SMK+HS)
While the PROTOLON(FL) excels in flat reeling applications, its counterpart, the PROTOLON (SMK+HS) (N)TSKCGEWOEU, is designed for round cable applications with additional high-strength aramid fibers. Key differences include:
Shape: The flat PROTOLON(FL) is ideal for space-constrained installations, while the round SMK+HS suits applications requiring torsional stress resistance.
Mechanical Strength: The SMK+HS variant offers enhanced protection for extreme conditions, such as heavy-duty mining operations.
Application Suitability: PROTOLON(FL) is optimized for flat reeling systems, while SMK+HS is better for complex reeling paths with torsional forces.
For South African mining operations, where equipment often faces extreme torsional stress, the SMK+HS variant may be preferred. However, for port cranes and conveyor systems, the PROTOLON(FL)’s flat design offers superior performance.
Why Choose PROTOLON(FL)?
The PROTOLON(FL) cable offers several compelling advantages:
Durability: Its robust construction ensures longevity in harsh industrial environments.
Weather Resistance: UV, ozone, and moisture resistance make it suitable for South Africa’s diverse climates, from coastal humidity to inland heat.
Flexibility: The flat design and EPR insulation allow for smooth operation in dynamic systems.
Versatility: Supports a wide range of applications, from cranes to excavators, meeting diverse industrial needs.
