Elastomeric Cables are electrical cables manufactured using elastomer-based insulation compounds, commonly referred to as rubber insulation. Historically, rubber was the earliest insulating material used in electrical wiring systems. Over time, natural rubber has largely been replaced with advanced synthetic elastomers that provide superior performance, durability, and safety.
The primary purpose of insulation in these cables is to prevent electrical leakage and short circuits by isolating conductors from each other and from the surrounding environment. Due to their reliability and flexibility, Elastomeric Cables are widely used in industries such as water treatment plants, renewable energy installations, nuclear facilities, and mining operations where safety and endurance are critical.
High-tension variants of Elastomeric Cables are specifically designed for demanding conditions involving elevated temperature and pressure. These cables are capable of operating at voltages exceeding 1000 volts and are valued for their excellent elasticity and tensile strength. On the other hand, low-tension control cables typically operate below 1000 volts and are known for heat resistance, moisture protection, and their ability to transmit heavy electrical loads without performance loss.
Flexible elastomeric insulated cables are especially popular because of their adaptability in dynamic environments. They resist environmental stress, chemicals, and mechanical wear, making them suitable for industrial machinery and automation systems. Modern manufacturing processes combine high-grade raw materials with advanced technology to ensure consistent product quality and long service life.
Apart from standard cables, specialized variants are also available. Double cotton coated ropes, made from braided copper conductors, are commonly used in transformers and electrical instruments up to 220 kV capacity. Similarly, elastomeric battery cables used in railway and automotive sectors are designed to withstand acids, saltwater, and abrasion, ensuring long-term operational reliability.
Medium and low voltage elastomeric insulated cables regulate power flow across various electrical systems. These cables often use EPR or XLPE insulation to provide aging resistance and mechanical strength. Composite elastomeric cables designed for voltages above 1100 volts consist of multiple conductors twisted together to deliver stable electrical performance.
A major advantage of Elastomeric Cables is customization. They can be tailored according to voltage rating, insulation thickness, and application requirements, making them suitable for diverse industrial installations where performance and safety cannot be compromised.
