Flat cable for elevator traveling

【Flat Cable for Elevators, Trailing Control Cable for Lifts】

As a core product of Shanghai Oukesen Wire & Cable Co., Ltd., flat cables for elevators and trailing control cables for lifts play a pivotal role in modern elevator systems. With the increasing height of urban buildings, the safe, stable and long-lasting operation of elevators has become a key focus of the industry. This article will conduct an in-depth analysis of the design concepts and technical details of these two types of cables from multiple dimensions such as materials, manufacturing processes, application scopes, precautions, installation and maintenance, helping readers gain a more comprehensive understanding of elevator cables and providing references for purchasing.

I. Material Advantages of Flat Cables for Elevators and Cables for Lifts

Flat cables for elevators and trailing control cables for lifts are usually made of high-quality copper core conductors and environmentally friendly flame-retardant materials, which are directly related to their conduction efficiency and safety. Specifically:

• Conductor Material: Oxygen-free copper or high-purity copper is generally selected, which has the advantages of low resistance, good toughness and not easy to oxidize, ensuring the stability and safety of current transmission.

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

• Sheath Material: The outer sheath is mostly polyvinyl chloride (PVC) or polyurethane (PU), which has wear resistance, ultraviolet resistance and corrosion resistance, and can withstand the complex environment in the elevator shaft.

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

The reasonable combination of these materials ensures that elevator cables have excellent mechanical strength and electrical performance, meeting the needs of elevators for fast, high-frequency and high-current operation.

II. Fine Manufacturing Process Flow

Shanghai Oukesen Wire & Cable Co., Ltd. combines high-tech processes with strict quality control to ensure every link of elevator cables is perfect. The main manufacturing steps include:

1. Copper Core Selection and Drawing Processing - Advanced copper wire drawing equipment is used, and multiple drawing processes ensure uniform copper wire diameter, enhancing conductivity.

2. Insulation Extrusion - The insulation layer is evenly wrapped around the conductor through a precision extruder, with consistent thickness, ensuring compliance with voltage resistance standards.

3. Multi-core Arrangement and Forming - The core wires inside the cable are arranged flat according to design requirements, ensuring flexibility and tensile strength to adapt to the bending and traction requirements of elevators.

4. Outer Sheath Coating - The outer sheath adopts a double-layer or multi-layer structure, and after extrusion forming, automatic detection equipment is used to detect dimensions and abnormal points.

5. Flame Retardancy Test - All cables leaving the factory must pass the flame retardancy test to ensure compliance with national standards and industry safety specifications.

This series of complex processes ensures the stability and safety of elevator cable performance, not only meeting the GB/T 19666 standard but also reaching relevant international certification requirements.

III. Application Scopes of Elevator Cables for Multiple Scenarios

As key components of elevator systems, flat cables for elevators and trailing control cables for lifts have a wide range of applications:

• Elevator Main Control System: Connects the elevator host and control cabinet, responsible for elevator lifting signal transmission and safety protection.

• Car Trailing Cables: Adapt to repeated bending and stretching of the car movement, and frequent switching of working conditions without obvious wear.

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

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

• Other Automation Facilities: Such as electrical connections for automatic door systems, safety monitoring, etc.

Its good flexibility and wear resistance make it perform well in high-frequency motion occasions, suitable for various important engineering projects such as large residential buildings, commercial complexes, subway stations and hospitals.

IV. Key Precautions for Using Elevator Cables

Although elevator cables attach importance to materials and processes, details must also be paid attention to in actual use, including:

• Rationally design the laying path, avoid sharp-angle bending and excessive stretching, and prevent internal conductor breakage.

• Avoid crossing elevator cables with high-voltage equipment, reduce electromagnetic interference, and ensure signal stability.

• Regularly check the cable insulation layer to prevent safety risks caused by insulation aging and damage.

• For multi-layer cables, ensure good inter-layer insulation to avoid short circuits or arc phenomena.

• In environments with corrosive media, corrosion-resistant sheaths must be selected to extend service life.

• During installation, national elevator and cable specifications must be followed, and construction and connection must be standardized.

Only with correct use and maintenance can the safety performance of elevator cables be fully utilized, ensuring the long-term stable operation of the elevator system.

V. Installation Technology and Maintenance Suggestions

Shanghai Oukesen Wire & Cable Co., Ltd. recommends implementing the following standards during the installation of elevator cables:

1. Lay strictly according to the design drawings, ensure the cable has moderate tension, and avoid uneven force.

2. Due to the limited space in the elevator shaft, special fixing brackets must be used for cables to prevent shaking and wear.

3. Cable joints must use joint boxes to ensure stable contact and dust and moisture resistance.

4. After installation, cable voltage withstand and insulation performance tests should be conducted, and the cable can be put into use only after confirming no abnormalities.

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

6. Special attention should be paid to the winding condition of car trailing cables to avoid tangling or fracture.

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