Wanma FR XLPE Compound Passes Provincial New Product Appraisal

The flame- retardant S i-XLPE insulation material which follows UL standards has passed the evaluation of "Zhejiang Province Industrial New Product ", has been awarded the " Zhejiang Province Industrial New Product Certificate " by the Zhejiang Provincial Department of Economy and Information Technology.

The flame-retardant Si-XLPE insulation material, which is utilized in accordance with UL standards, possesses an innovative formula design and manufacturing process. It has secured a utility model patent, demonstrating its superior flame retardancy and exceptional insulation capabilities. The acceptance evaluation team has unanimously concurred that this novel product has successfully undergone the provincial new product appraisal, indicating that its product technology is at the forefront in China.

This product exhibits a 50% enhancement in tensile strength and possesses a volume resistivity that is several hundred to several thousand times higher than the commonly utilized low smoke halogen-free flame-retardant cable material currently available in the market. It possesses superior electrical, mechanical, and extrusion properties, along with a broad range of processing parameters, rendering it suitable for diverse extruder types. Customers are not required to introduce new equipment for its application and can directly produce using existing equipment, thereby ensuring exceptional ease of operation. Furthermore, once assembled into a cable, this product can successfully pass the VW-1 and FT2 flame retardant tests. Currently, it is primarily targeted towards overseas markets that adhere to UL standards, finding application in wires such as XHHW-2, XHHW, XHH, and others that comply with UL standards like UL44 and UL1581.

Wanma Macromolecule, as a pioneering entity in the realm of wire and cable new materials, remains steadfast in adhering to the ideology of innovation-driven development. It is committed to the ongoing pursuit of research and development, aiming to yield increasingly high-performance and superior-quality polymer material products.

Wanma Cable Compound for energy storage cable supporting the green and low-carbon future

With the booming development of renewable energy and the increasing demand for electricity, energy storage technology has become one of the important means to balance energy supply and demand. As a key part of energy storage system, energy storage cable plays an important role in connecting and transmitting energy.

Energy storage cables are used in a wide range of fields, including transmission lines of energy storage system, battery components and internal connections of energy storage equipment, and can also be used for the storage and transmission of energy sources such as solar and wind energy, as well as the connection of electric vehicle charging equipment and battery modules. As a special cable for energy storage system, many factors need to be considered in the design and manufacturing process, including bearing capacity, resistance and loss, heat resistance and corrosion resistance,etc.

In order to meet the special needs of energy storage cables, the choice of materials is crucial. According to the CQC1143 & PPP58049A of battery connection cable for electric energy storage system, the peak voltage level in the power energy storage system is DC 1500V DC system, and the highest temperature resistance level is 125℃. The current insulation and sheath materials of energy storage cables used are mainly low smoke non-halogen-free flame retardant and heat resistant 125℃ cross-linked polyolefin (WDZ-YJ-125). The irradiation treatment process of cables prepared by this kind of materials is complex, the cost is high, and the cables are difficult to recycle, leading to the waste of resources. Therefore, it is particularly urgent to develop a non-cross-linking, high temperature resistance, high flexibility, good elasticity, strong flame retardant performance and outstanding cost-effective performance products.

Wanma 125℃ PVC energy storage cable can meet the requirements of different customers for the softness, high and low temperature resistance, and combustion performance of PVC energy storage cables.

Wanma Compoud always take scientific and technological innovation as the core, constantly increase investment in RESEARCH and development, explore cutting-edge technologies, launch green and low-carbon innovative products, and promote the company to unswervingly move forward on the road of high-quality development.
