In power systems, cable accessories are a key link in ensuring stable power transmission, and a high-quality dedicated silicone rubber is the core to improving the performance of cable accessories. Recently, the IOTA HTV 326 series of silicone rubber for cable accessories has stood out in the production of indoor and outdoor cold-shrink terminations, sheaths and other products, thanks to its advantages such as voltage resistance, high toughness and easy processing, providing strong support for power safety. The core advantage of this silicone rubber lies in its excellent voltage resistance. It can withstand a breakdown strength of up to 24.3KV/mm, just like putting a layer of "insulation armor" on cable accessories. Even when working in a medium-voltage environment for a long time, it can effectively isolate current and avoid risks such as leakage and short circuit. What's more noteworthy is that its dielectric constant is stably maintained at 3.03, and the loss factor is only 0.0029. This means extremely low power loss during power transmission, which not only ensures electricity safety but also improves energy utilization efficiency. It is particularly suitable for power scenarios with strict requirements on insulation performance. Its high tensile strength and high elongation make it superior in durability. During the installation and use of cable accessories, stretching and bending are inevitable. This silicone rubber has a tensile strength of 10.0MPa, which can withstand large pulling forces without breaking easily. Its elongation rate is as high as 700%, so even if it is stretched significantly, it can quickly rebound and return to its original shape without permanent deformation. For example, in outdoor cold-shrink terminations, when harsh weather causes slight displacement of cables, the silicone rubber material can deform synchronously and always wrap the cables tightly, avoiding protection gaps caused by material cracking. The injection molding processing method also brings great convenience to production. Traditional materials are difficult to mold and prone to problems such as bubbles and cracks. However, this silicone rubber is compatible with the injection molding process, which can accurately fill every detail of the mold and quickly produce cable accessories with complex shapes. This not only improves the product qualification rate but also significantly shortens the production cycle. At the same time, it has passed the RoHS test and does not contain harmful substances such as lead and mercury. It not only meets environmental protection requirements but also avoids pollution to soil and water sources, contributing to the construction of green power. From the perspective of typical data, the two models HTV 32642 and HTV 32643 have stable performance, small permanent set at break, and their tracking resistance reaches grade 1A3.5, which can adapt to complex environments such as humidity and dust. Whether it is for the termination protection of outdoor high-voltage cables or the sheath production of indoor cables, this silicone rubber can provide reliable support and become a "solid backing" for the safe operation of power systems.
