NSHTOEU Low Voltage Reeling Cable Flexible Rubber Reeling Cable for Medium Mechanical Stresses

Introduction

NSHTOEU is a high-performance low voltage reeling cable engineered for applications subjected to medium mechanical stresses. Designed to meet rigorous industry standards, this cable delivers reliable power and control transmission while withstanding the demanding conditions of reeling and unreeling operations. It conforms to DIN VDE 0250-814 standard, ensuring consistent quality, safety, and performance across diverse operational environments.

Construction & Material Design

Every layer of the cable is carefully designed to maximize flexibility, durability, and electrical performance. The detailed structure and material specifications are as follows:

1. Conductor

• Material: Tinned copper

• Flexibility Class: Class 5, in accordance with DIN EN 60228 / DIN VDE 0295

• Feature: Highly flexible, resistant to corrosion, and suitable for continuous bending and movement

2. Insulation

• Material: Rubber compound type 3GI3

• Standard Compliance: DIN VDE 0207-20

• Performance: Provides excellent electrical insulation and thermal stability

3. Core Identification

• Up to 5 cores: Color-coded following DIN VDE 0293-308

• 6 cores and above: Black insulation with white numerical markings for easy identification

4. Core Arrangement

• Cores are twisted with a short length of lay to enhance flexibility

• Central filler (plastic or textile) included; may be covered with rubber when necessary to maintain round shape and structural stability

5. Inner Sheath

• Material: Rubber compound type 5GM3

• Standard Compliance: DIN VDE 0207-21

• Function: Binds core assembly and provides additional mechanical protection

6. Reinforcement Layer

• Structure: Wide-meshed polyester braid embedded within the sheath

• Benefit: Distributes mechanical stress, improves tensile strength, and resists torsional deformation during reeling operations

7. Outer Sheath

• Material: Extruded rubber compound type 5GM5

• Standard Compliance: DIN VDE 0207-21

• Key Properties: High resistance to abrasion, tearing, and oil; ensures long service life in harsh environments

8. Outer Marking

• Sheath color: Black

• Imprint content: NSHTOEU-J (number of cores) × (cross-section), plus continuous meter marking for installation and length tracking
