Polyurethane PUR downhole logging equipment signal transmission cable

Specialized Polyurethane Exploration Equipment Cable, Downhole Logging PUR Signal Transmission Cable With the advancement of mining and oil exploration technologies, the performance requirements for signal cables in downhole logging equipment have become increasingly stringent. Shanghai Okesen Wire & Cable Co., Ltd. specializes in the research, development, and production of specialized polyurethane exploration equipment cables, offering PUR signal transmission cables suitable for downhole logging to ensure stable signal transmission in complex environments. This article will provide an in-depth introduction to the application scope, installation methods, precautions, material composition, and manufacturing processes of these cables from multiple perspectives, helping you gain a comprehensive understanding and select the appropriate signal transmission solution.

I. Application Scope of Polyurethane Signal Cables

Specialized polyurethane exploration equipment cables, particularly downhole logging PUR signal transmission cables, are widely used due to their wear resistance, oil resistance, corrosion resistance, and high flexibility. Applications include:

• Signal transmission for downhole measurement equipment in mines, ensuring accurate data collection.

• Real-time data transmission for logging instruments during oil drilling operations, suitable for high-temperature and high-pressure environments.

• Electrical signal transmission for various mobile and fixed detection equipment in geological exploration.

• Precision signal line requirements in industrial automation and monitoring systems.

Designed to meet industry standards, these cables provide stable transmission performance under complex working conditions such as mechanical stretching and torsional vibration, significantly reducing the risk of equipment downtime due to cable failure.

II. Installation Methods and Standards

The installation of downhole logging cables must strictly adhere to relevant standards to maximize cable performance:

1. Maintain Cable Bending Radius: Avoid excessive bending; it is recommended that the bending radius be no less than 8 times the cable’s outer diameter to prevent internal conductor breakage or insulation damage.

2. Fixation Method: Use specialized cable clamps or trays to avoid additional tension from hanging cables.

3. Protective Layer Setup: Install protective sleeves or conduits at sharp edges or areas prone to abrasion to prevent damage to the polyurethane sheath.

4. Prevent Water Ingress and Chemical Corrosion: Identify high-humidity environments during installation and use waterproof connectors and anti-chemical corrosion measures as necessary.

5. Labeling and Grounding: Clearly label signal cable ports for ease of installation and maintenance. Grounding must comply with downhole safety standards.

III. Precautions During Use

To extend the service life of the cable, pay attention to the following details during use:

• Avoid exposing the cable to temperatures beyond its rated range; the polyurethane sheath is generally suitable for -40°C to +80°C.

• Prevent mechanical impacts and repeated bending; although polyurethane materials are wear-resistant and flexible, extreme conditions can still degrade performance.

• Regularly inspect the cable for cuts, abrasions, or deformations to identify potential hazards early.

• Keep cable connection points clean and secure to avoid poor contact and signal attenuation.

Only with proper usage habits can the long-term stable operation of downhole logging equipment be ensured.

IV. Advantages of Product Materials

The specialized polyurethane exploration equipment cables produced by Shanghai Okesen use high-quality PUR (polyurethane) material for the sheath, offering the following advantages:

• Excellent Wear Resistance: The polyurethane sheath has a low friction coefficient, resisting scratches from downhole rocks and mechanical wear.

• High Elasticity and Tear Resistance: Withstands repeated bending and stretching without breaking easily.

• Oil and Chemical Corrosion Resistance: Polyurethane material resists acids, alkalis, and oil sludge, ensuring the safety of the cable’s internal structure.

• Strong Waterproof Performance: The dense surface prevents water ingress, ensuring stable signal transmission.

• Environmentally Friendly and Non-Toxic: The material complies with environmental standards such as RoHS, ensuring safety during construction and use.

In addition to the sheath, the conductor is made of high-purity oxygen-free copper, enhancing conductivity and reducing signal attenuation and interference during transmission.

V. Manufacturing Process and Quality Control

From core selection to cable formation and sheath extrusion, Shanghai Okesen follows a rigorous manufacturing process:

1. Conductor Manufacturing: Uses multi-strand high-purity copper wires for both conductivity and flexibility.

2. Uniform Insulation Coating: Employs polyethylene or polyvinyl chloride insulation materials with uniform thickness to prevent leakage and signal attenuation.

3. Multi-Layer Braiding Design: Utilizes aluminum foil and copper braiding layers to resist electromagnetic interference and ensure reliable signal transmission.

4. Polyurethane Sheath Extrusion: Uses advanced extrusion equipment to enhance sheath adhesion and improve overall mechanical performance.

5. Strict Testing: Includes voltage resistance tests, bending tests, environmental aging tests, and signal transmission performance tests to ensure the quality of every batch of products.

Over the years, the company has been committed to continuous process improvement, optimizing cable performance based on customer feedback, and earning industry recognition.
