What is Custom Cabling?

Custom cabling refers to the manufacturing process of designing and producing cables tailored to specific requirements and applications. Unlike standard off-the-shelf cables, custom cables can be customized in terms of length, connectors, insulation materials, shielding, and overall configuration to meet the unique needs of a particular system or equipment.
What is an Overmolded Cable?

An overmolded cable, also known as a custom molded cable, is a type of cable assembly where a protective layer of thermoplastic material is molded over the cable and connectors to provide additional strength, flexibility, and resistance to environmental factors such as moisture, chemicals, and mechanical stress. Overmolding enhances the durability and reliability of the cable, making it ideal for use in rugged environments like oil and gas drilling operations.
What is a Custom Cable Assembly?

A custom cable assembly is a complete solution that includes custom-designed cables, connectors, terminations, and other components tailored to meet specific application requirements. These assemblies are designed to ensure optimal performance, reliability, and safety in critical systems such as drilling instrumentation in the oil and gas industry.

Benefits of Custom Molded Cables in the Oil and Gas Industry

Materials Used for Custom Molded Cables in the Oil and Gas Industry

Custom molded cables for the oil and gas industry are typically constructed using high-quality materials that offer excellent resistance to abrasion, chemicals, extreme temperatures, and other environmental hazards. Common materials used in these cables include:

  • PVC (Polyvinyl Chloride): PVC is a versatile and cost-effective material that provides good insulation properties and resistance to moisture and chemicals.
  • TPU (Thermoplastic Polyurethane): TPU offers superior flexibility, durability, and resistance to abrasion and harsh chemicals, making it suitable for demanding applications in the oil and gas industry.
  • FEP (Fluorinated Ethylene Propylene): FEP is a high-performance material known for its exceptional thermal stability, chemical resistance, and low friction coefficient, making it an ideal choice for custom molded cables exposed to high temperatures and chemical environments.
  • Silicone: Silicone is a flexible and heat-resistant material that offers excellent performance in extreme temperature conditions. It is also resistant to UV radiation, ozone, and moisture, making it suitable for outdoor applications in the oil and gas industry.
  • Polyethylene: Polyethylene is a durable and lightweight material that provides good electrical insulation and resistance to moisture and chemicals. It is commonly used in custom molded cables for underground and submersible applications.

Durable and Suitable for Harsh Environmental Conditions

Custom molded cables are designed to withstand the harsh conditions of the oil and gas industry, including exposure to extreme temperatures, high pressure, vibration, and corrosive chemicals. Overmolding provides a protective barrier that seals the cable and connectors, preventing moisture ingress, dust contamination, and physical damage. This enhanced durability ensures that custom molded cables can perform reliably in challenging environments without compromising signal integrity or power transmission.

Designed to Withstand Extreme Temperatures, Pressure, and Chemicals

Custom molded cables can be specifically engineered to withstand extreme temperatures ranging from -40°C to 150°C or higher, making them suitable for both cold and hot environments encountered in oil and gas drilling operations. Additionally, these cables can be designed to withstand high-pressure conditions commonly found in deep-sea drilling applications. They are also resistant to a wide range of chemicals, fuels, and hydraulic fluids, ensuring long-term performance and reliability in demanding industrial settings.

Customizable in Length, Connectors, and Configuration

One key advantage of custom molded cables is their high degree of customization. OEM drilling instrumentation manufacturers like Contact Instruments can tailor the cables to meet specific length requirements, connector types (circular or rectangular connectors), and configurations (straight, angled, Y-split, etc.). This level of customization allows for seamless integration with existing equipment and ensures optimal cable management in complex systems.

Industry Standards and Regulations

Custom molded cables for the oil and gas industry must adhere to various industry standards and regulations to ensure safe and reliable operation. Some of the common standards that these cables may need to meet include:

  • API (American Petroleum Institute) standards for equipment used in oil and gas exploration and production
  • ATEX (Atmosphères Explosibles) directive for equipment used in potentially explosive atmospheres
  • IEC (International Electrotechnical Commission) standards for electrical and electronic devices in hazardous environments
  • UL (Underwriters Laboratories) certification for compliance with safety and performance requirements

Design and Manufacturing Considerations

Designing and manufacturing custom molded cables for a specific application in the oil and gas industry typically involves several key steps, including:

Requirement Analysis

Understanding the technical specifications, environmental conditions, and performance requirements of the system in which the cables will be used.

Cable Design

Developing a customized cable design that meets the length, connectors, materials, and configuration requirements.

Prototyping

Creating a custom molded cable assembly prototype for testing, validation, and approval.

Production
