Elevator trailing flat cable

【Elevator Flat Cable, Lift Traveling Control Cable】

As a core product of Shanghai Okesen Wire & Cable Co., Ltd., elevator flat cables and lift traveling control cables play a crucial role in modern elevator systems. With the continuous increase in urban building heights, the safe, stable, and durable operation of elevators has become a key focus in the industry. This article will delve into the design philosophy and technical details of these two types of cables from multiple dimensions, including materials, manufacturing processes, application scope, precautions, and installation and maintenance, to help readers gain a comprehensive understanding of elevator cables and provide reference for selection.

1. Material Advantages of Elevator Flat Cables and Lift Cables

Elevator flat cables and lift traveling control cables typically use high-quality copper core conductors and environmentally friendly flame-retardant materials, which directly affect their conduction efficiency and safety. Specifically:

• Conductor Material: Oxygen-free copper or high-purity copper is commonly selected, offering advantages such as low resistance, high toughness, and resistance to oxidation, ensuring stable and safe current transmission.

• Insulation Material: High-molecular polyethylene (PE) or polyvinyl chloride (PVC) insulation is used, with options for flame-retardant, high-temperature-resistant, and oil-resistant materials to meet the special environmental requirements of long-term elevator operation.

• Sheath Material: The outer sheath is mostly made of polyvinyl chloride (PVC) or polyurethane (PU), offering wear resistance, UV resistance, and corrosion resistance, capable of withstanding the complex environment of elevator shafts.

• Environmental Performance: All materials comply with the ROHS directive, being lead-free and halogen-free, ensuring environmental safety during use and disposal.

The rational combination of these materials ensures that elevator cables possess excellent mechanical strength and electrical performance, meeting the demands of fast, high-frequency, and high-current elevator operation.

2. Fine Manufacturing Process

Shanghai Okesen Wire & Cable Co., Ltd. combines high-tech processes with strict quality control to ensure excellence in every step of elevator cable production. The main manufacturing steps include:

1. Copper Core Selection and Drawing Processing—Advanced copper wire drawing equipment is used, with multiple draws to ensure uniform copper wire diameter and enhance conductivity.

2. Insulation Extrusion—Precision extruders are used to evenly coat the conductor with an insulation layer, ensuring consistent thickness and meeting voltage resistance standards.

3. Multi-Core Arrangement and Shaping—The internal cores of the cable are arranged flat according to design requirements, ensuring flexibility and tensile strength to meet the bending and traction demands of elevators.

4. Outer Sheath Coating—The outer sheath adopts a double or multi-layer structure, with automatic detection equipment used for size and anomaly inspection after extrusion molding.

5. Flame Retardancy Testing—All finished cables must undergo flame retardancy testing to ensure compliance with national standards and industry safety regulations.

This series of complex processes ensures the stable performance and safety of elevator cables, not only meeting the GB/T 19666 standard but also achieving international certification requirements.

3. Application Scope of Elevator Cables for Multiple Scenarios

As key components of elevator systems, elevator flat cables and lift traveling control cables have a wide range of applications:

• Elevator Main Control System: Connects the elevator main unit to the control cabinet, responsible for transmitting elevator movement signals and safety protection.

• Car Traveling Cable: Adapts to the repeated bending and stretching of the car's movement, frequently switching working states without significant wear.

• Lift Control Lines: Used in industrial and commercial lifting platforms to achieve multi-point control and communication.

• Shaft Lighting and Ventilation Equipment Power Supply: Ensures the normal operation of auxiliary equipment in the elevator shaft.

• Other Automated Facilities: Such as electrical connections for automatic door systems and safety monitoring.

Their excellent flexibility and wear resistance make them perform exceptionally well in high-frequency motion scenarios, suitable for various large-scale residential, commercial complexes, subway stations, hospitals, and other critical engineering projects.

4. Key Precautions for Using Elevator Cables

Although elevator cables emphasize materials and processes, attention to detail is equally important during actual use, including:

• Design a reasonable laying path to avoid sharp bends and overstretching, preventing internal conductor breakage.

• Avoid crossing elevator cables with high-power electrical equipment to reduce electromagnetic interference and ensure signal stability.

• Regularly inspect the cable insulation layer to prevent insulation aging and damage that could cause safety risks.

• For multi-layer cables, maintain good inter-layer insulation to avoid short circuits or arcing.

• In corrosive environments, choose corrosion-resistant sheaths to extend service life.

• Follow national elevator and cable regulations during installation, ensuring standardized construction and connections.

Only with proper use and maintenance can the safety performance of elevator cables be fully realized, ensuring the long-term stable operation of elevator systems.

5. Installation Techniques and Maintenance Recommendations

Shanghai Okesen Wire & Cable Co., Ltd. recommends adhering to the following standards during the installation of elevator cables:

1. Lay cables strictly according to design drawings, ensuring moderate tension to avoid uneven stress.

2. Due to the confined space in elevator shafts, use dedicated fixing brackets to prevent shaking and wear.

3. Use junction boxes for cable connections to ensure stable contact and protection against dust and moisture.

4. After installation, perform voltage resistance and insulation performance tests on the cables to confirm no abnormalities before putting them into use.

5. During regular maintenance, check the cable surface for cracks and damage, and replace damaged cables promptly.

6. Pay special attention to the winding of car traveling cables to avoid tangling or kinking.

Good installation and maintenance not only enhance the overall performance of elevators but also extend equipment service life and reduce maintenance costs.

6. Comprehensive Perspective and Future Outlook

The performance of elevator flat cables and lift traveling control cables directly determines the safety and reliability of elevator systems. Relying on its deep expertise in material science and process technology, Shanghai Okesen Wire & Cable Co., Ltd. continuously optimizes product design and production processes, balancing flexibility and high strength to meet the diverse needs of different elevators and lifting equipment.
