With the advancement of global carbon emission targets, the development of clean energy is unstoppable. Offshore wind power has developed rapidly due to its unique advantages such as large size and large single-unit capacity. However, it is accompanied by higher construction technical difficulties and more complex construction environments than onshore wind power. In addition, offshore wind farms are gradually developing from offshore to deep and offshore. The environment is more complex than offshore, and the demand for daily maintenance is becoming increasingly stringent, and the requirements for power equipment are also getting higher and higher. Therefore, in order to help meet the construction needs of offshore wind farms, especially the construction of offshore wind power, ABB has developed the SoliMold series 72.5kV cable accessories, which are designed for the 38/66/72.5 kV voltage level of offshore wind power and are mainly used for electrical equipment in offshore wind turbine towers.
The new cable accessories use imported EPDM rubber as raw material, which has excellent seawater corrosion resistance, flame retardant properties and anti-fungal properties, and can maintain long-term stability and reliability in harsh marine environments. At the same time, it also has good compression resistance, tear resistance, friction resistance and other characteristics to ensure that the product can withstand various complex mechanical stresses during use.
In addition, in order to meet the installation needs of equipment such as switch cabinets and branch boxes of different sizes, the SoliMold series 72.5kV cable accessories adopt a small and compact design. This design not only makes the product easier to install and transport, but also greatly improves the space utilization of the equipment, providing more convenience for the construction of offshore new energy facilities.
In terms of electrical performance, the thickness of the outer shielding layer of the product is greater than 2mm, the grounding resistance is less than 1000Ω, and there is no need for a minimum safe clearance requirement, thus ensuring the safety and reliability of the product during use. In addition, the rear connector and the front connector of the product adopt a matching design, without the need for a connector, the installation length is short, and it can be installed in a smaller space, further improving the flexibility and applicability of the product.
In order to ensure the quality of each product, ABB has conducted 100% withstand voltage and partial discharge tests on all products. This quality assurance measure not only reflects ABB's strict control of product quality, but also provides customers with more reliable product guarantees.
Dr. Dong Gang, head of ABB Electrical China's installation products, said, "ABB SoliMold series 72.5kV cable accessories overcome various R&D technical difficulties. With its stable and reliable raw material formula, flexible interface matching design, and effective protection against erosion in harsh offshore application environments, it plays the role of "reliable connection" between cables in wind turbine towers and transformers, switch cabinets, and between wind turbines and other important connection nodes. It has been applied and operated stably in domestic offshore wind power projects. With the trend of increasingly saturated installed capacity of onshore new energy power generation, offshore has become the forefront of large-scale development of wind power. Looking to the future, the booming new energy industry will surely leave behind the innovation of ABB's installation products."
The launch of the new 72.5kV cable accessories not only provides high-quality and reliable product options for the new energy industry, but also injects new vitality into the development of the offshore new energy industry. In the future, ABB will continue to provide customers with safer, more reliable and more efficient overall solutions for the power transmission and distribution industry through continuous technological innovation and product development, and contribute to global energy transformation and sustainable development.
