Deep-sea waterproof benchmark Waterproof cable Water Resistant Cable application

Water Resistant Cable is a cable specially designed to work in humid environments or in direct contact with water. This type of cable pays special attention to waterproof performance in both structural design and material selection to ensure that it can work normally underwater or in high humidity environments without affecting electrical performance. Below TST CABLES will give you a detailed introduction to the characteristics, advantages, industry applications, testing standards, manufacturing processes and technological development trends of watertight cables.

Structure of Watertight Cable
Watertight cables usually consist of the following parts:

Conductor: Usually copper or tinned copper to ensure good conductivity.

Insulation layer: Water-resistant materials such as cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR) are used to provide good electrical insulation.
Waterproof layer: Waterproof materials such as polyurethane (PU) or special synthetic rubber are used to prevent moisture penetration.
Shielding layer: Used to reduce electromagnetic interference (EMI) or radio frequency interference (RFI) and protect the internal conductor from external interference.
Reinforcement: Such as steel wire or fiber, to improve the mechanical strength and bending performance of the cable.
Sheath layer: The outermost layer of protection, usually made of oil-resistant, wear-resistant, and weather-resistant materials such as polyvinyl chloride (PVC) or polyurethane (PU).

Advantages of watertight cables
Waterproof performance: It can effectively prevent moisture from entering the cable to ensure that the electrical performance is not affected.
Durability: It has a long service life in humid or underwater environments.
Safety: Reduce short circuit or electric shock accidents caused by moisture.
Reliability: It can maintain stable electrical transmission performance even in harsh environments.

Application of watertight cables in the industry
Marine engineering: Suitable for laying submarine cables, internal wiring of ships, etc.
Water conservancy facilities: Power transmission in water conservancy facilities such as reservoirs, dams, and pumping stations.
Industrial production: Industrial environments such as chemical plants and sewage treatment plants that require water-resistant cables.
Construction industry: Electrical wiring in humid areas such as underground garages and around swimming pools.
Agricultural irrigation: Power and signal transmission in farmland irrigation systems.

Water Resistant Cable test standards
Common Water Resistant Cable test standards include but are not limited to:

IEC 60228: Standards for conductors for fixed laying.
IEC 60331: Test standard for cables to maintain circuit integrity under fire conditions.
IEC 60332: Test standard for the combustion performance of cables in flames.
GB/T 12706: Standard for extruded insulated power cables with rated voltages of 1kV (Um=1.2kV) to 35kV (Um=40.5kV).
ASTM D2240: Standard method for measuring material hardness (Shore durometer).

Water Resistant Cable manufacturing process
The manufacturing of watertight cables usually involves the following steps:

Conductor production: Copper or copper alloy is drawn into wires of the required specifications.
Insulation layer extrusion: The insulation material is evenly wrapped around the outside of the conductor using an extruder.
Waterproof layer treatment: A waterproof layer is formed outside the insulation layer by dipping or spraying.
Shielding layer winding: Use metal wire or metal tape to wrap around the outside of the waterproof layer.
Sheath extrusion: The last step is to extrude the outer sheath material and cover it on the surface of the cable.

Development trend of Water Resistant Cable technology
Environmentally friendly materials: Develop more environmentally friendly and recyclable materials to reduce the impact on the environment.
Intelligent monitoring: IoT and artificial intelligence integrate sensor technology to monitor the working status of cables and improve operation and maintenance efficiency.
Resistant to extreme environments: Research watertight cables that can adapt to wider temperature ranges and pressure conditions.
Lightweight design: New materials and new processes are used to reduce the weight of cables and facilitate laying.
Multifunctional integration: Combine multiple functions such as communication and sensing to expand the application field.
Watertight cables fully consider the importance of waterproof performance during the design and manufacturing process, and play a key role in different industries. With the continuous development of technology, future watertight cables will be more intelligent, environmentally friendly, and able to adapt to more complex application environments.
