High-strength tension element: Built-in high-strength tension element, the tested load capacity can reach 15,000% of DIN VDE 0298 standard, suitable for extreme working conditions such as deep well drilling

1. Speciality cables/Loop

Environmental adaptability optimization
Use flame-retardant and high-temperature resistant materials to meet the needs of high-temperature and high-corrosion environments underground58.
Dynamic performance verification
Through mechanical tests such as U-bending tests, ensure the fatigue resistance of cables under long-distance movement and large outer diameter conditions.

The life and maintenance cost of cables are affected by many factors, including materials, usage environment, and maintenance strategies, as follows:

Cable lifespan
Design life:The design lifespan of conventional cables is usually around 20 years, but the actual lifespan of high-quality cables can be extended to more than 30 years under normal load, no overload and stable environment conditions.

Lifespan of special cables/Loop:
Due to optimized materials and processes, high-performance cables such as BTTRZ can have a lifespan of 50-100 years6, which is suitable for scenarios with extremely high durability requirements (such as deep well drilling, high temperature environments, etc.).

Influencing factors:
Material properties: High-quality materials such as copper or aluminum core conductors and cross-linked polyethylene (XLPE) insulation layers can significantly extend the lifespan57.
Environmental conditions: High temperature, corrosive media or mechanical vibrations will accelerate aging and shorten the lifespan25.
Installation process: Standardized laying (such as avoiding excessive bending) can reduce the risk of physical damage24.
Maintenance cost
Initial investment and long-term cost
The purchase cost of high-quality cables is high, but due to their long life and low failure rate, the maintenance cost of the whole life cycle is lower 4.
Poor-quality cables are prone to aging, and frequent replacement leads to increased total costs and safety hazards 4.
Maintenance measures and costs
Regular inspection : 6KV cables need to be tested for withstand voltage at least once a year, and 380V cables need annual insulation tests. Preventive maintenance can reduce sudden failures 2.
Environmental management : Keeping cables clean, moisture-proof and anti-corrosion can reduce maintenance frequency 25.
Economic optimization
Selecting cables that match the scenario (such as using conductors with larger cross-sectional areas for medium and high voltage scenarios) can reduce energy consumption and maintenance requirements 78.
Using standardized cable models (such as aluminum alloy cables) can reduce customized procurement costs 7.

Comprehensive recommendations;
Selection strategy: Give priority to high-specification cables with XLPE insulation and copper core conductors, and match the voltage level (such as 0.6/1kV for low-voltage power distribution, 26/35kV for high-voltage power transmission)57.
Maintenance Plan: Develop a testing and replacement plan based on the cable life cycle, balancing cost and safety24.
Through reasonable selection and scientific maintenance, the cable system can achieve more than 30 years of stable operation, and the full-cycle cost can be reduced by about 20%~35%.
