Structural Design and Material Composition
2.1 Conductor Configuration: Precision in Power Distribution
The core of the Alumiinivoimakaapeli Tt Kabeli Tt Cables Nordic Amka 3X70+95 mm2 lies in its well-engineered conductor configuration. The three 70mm² conductors are primarily responsible for carrying the main power load, ensuring efficient transmission of electricity from the source to the end-users. These conductors are meticulously designed to handle the high current demands of medium to high-power applications, making them ideal for scenarios where a steady and robust power supply is crucial.
Complementing the main conductors is the 95mm² conductor, which serves a dual purpose as either a neutral conductor or a grounding line. The neutral conductor plays a vital role in balancing the electrical load in three-phase power systems, ensuring that the current is evenly distributed across the phases, thus preventing voltage imbalances that could damage electrical equipment. As a grounding line, it provides a safe path for excess current to flow into the ground in case of a fault, protecting both the electrical system and the individuals in its vicinity from potential hazards such as electric shocks and fires.
2.2 Aluminium Alloy Conductors: The Perfect Blend of Properties
The conductors of the Amka 3X70+95 mm2 cable are crafted from high-quality aluminium alloy, a material chosen for its exceptional combination of properties. Aluminium, by nature, is a lightweight metal, and when alloyed with other elements such as copper, magnesium, and silicon, it gains enhanced mechanical strength and electrical conductivity. This alloying process results in conductors that are not only strong enough to withstand the mechanical stresses of installation and operation but also efficient at transmitting electricity.
Compared to traditional Copper Conductors, the aluminium alloy conductors in this cable offer significant advantages. They are much lighter, which reduces the overall weight of the cable, making handling and installation easier and less labor-intensive. This is particularly beneficial in large-scale projects where the installation of heavy cables can be a logistical challenge. Additionally, aluminium is more abundant and cost-effective than copper, making the Amka 3X70+95 mm2 cable a more economical choice without compromising on performance. 2.3 TT (Tough Thermoset) Insulation and Sheathing: Protection Against the Elements
The insulation and sheathing of the Amka 3X70+95 mm2 cable are made from TT (Tough Thermoset) materials, which are specifically selected for their ability to withstand the harsh Nordic environment. Thermoset materials are known for their excellent thermal stability, Chemical Resistance, and mechanical strength. Once cured, they form a rigid and durable structure that does not soften or melt when exposed to high temperatures, unlike thermoplastic materials. The TT insulation surrounding each individual conductor provides a reliable barrier against electrical leakage, preventing short circuits and ensuring the safe transmission of electricity. It is designed to withstand extreme temperatures, ranging from -40°C to 90°C, which is critical in the Nordic regions where winter temperatures can plummet well below freezing and summer temperatures can rise to moderate levels. This wide temperature range ensures that the cable remains functional and safe throughout the year, regardless of the seasonal variations.
The outer sheathing, also made from TT material, serves as an additional layer of protection, shielding the internal conductors and insulation from physical damage, moisture, UV radiation, and chemical exposure. In coastal areas of the Nordics, where salt spray is a common issue, the sheathing's resistance to corrosion ensures that the cable remains intact and performs optimally. In industrial zones, where exposure to chemicals and pollutants is prevalent, the sheathing's chemical resistance prevents degradation, extending the cable's service life.
3. Performance Characteristics
3.1 Electrical Conductivity: Efficient Power Transmission
Electrical conductivity is a key performance 指标 (indicator) of any power cable, and the Amka 3X70+95 mm2 cable excels in this regard. The high-quality aluminium alloy conductors, combined with the optimized design of the cable, ensure low electrical resistance. Low resistance means that less energy is lost as heat during transmission, resulting in efficient power delivery. This is particularly important in the Nordics, where long-distance power transmission is common, and energy efficiency is a priority for both economic and environmental reasons.
The cable's ability to maintain high conductivity even under varying load conditions ensures that it can handle sudden increases in power demand without significant voltage drops. This stability is crucial for industrial applications where machinery and equipment require a consistent power supply to operate smoothly. It also ensures that commercial buildings and residential areas receive a reliable power supply, minimizing disruptions and ensuring the comfort and safety of occupants.

The TT insulation and sheathing's ability to withstand temperatures as low as -40°C ensures that the cable remains flexible and functional even in the coldest Nordic winters. This Flexibility prevents the cable from becoming brittle and cracking, which could lead to electrical faults. In addition, the insulation and sheathing are resistant to moisture, preventing water ingress that could cause short circuits and corrosion of the conductors. UV radiation from the sun can degrade many materials over time, but the TT sheathing of the Amka 3X70+95 mm2 cable is UV-resistant, ensuring that it does not become brittle or discolored when exposed to sunlight. This makes the cable suitable for outdoor installations, such as Overhead Power Lines and outdoor industrial facilities, where it is constantly exposed to the elements. 3.4 Corrosion Resistance: Longevity in Challenging Environments
Corrosion is a major threat to the longevity of Electrical Cables, especially in coastal areas and industrial zones where exposure to salt, chemicals, and pollutants is high. The Amka 3X70+95 mm2 cable is designed with corrosion resistance in mind, ensuring that it remains in good condition even in these challenging environments. The aluminium alloy conductors are treated with a protective coating that enhances their resistance to corrosion. This coating acts as a barrier, preventing moisture, salt, and chemicals from coming into direct contact with the aluminium, thus slowing down the corrosion process. The TT sheathing also provides an additional layer of protection against corrosion, as it is resistant to the chemicals and pollutants that can cause degradation.
This corrosion resistance extends the service life of the cable, reducing the need for frequent replacements and maintenance. It also ensures that the cable continues to perform optimally over time, maintaining its electrical conductivity and mechanical strength.
