Enhancing Thermoplastic Semicon Jacketing with SHAKUN ESCONTEK SP-PESC-566
Power cables in high and extra‑high voltage networks carry enormous responsibility. They must perform flawlessly for decades, often while facing harsh environmental and mechanical stresses. The integrity of these cables is essential for uninterrupted power distribution and operational safety. Even minor sheath defects can result in moisture ingress, insulation failure, or dangerous electrical faults.
At Shakun Polymers, we tackle this industry challenge with SHAKUN ESCONTEK SP-PESC-566. It is a high-performance thermoplastic semicon jacketing compound. It is specifically engineered to improve defect detection, enhance structural reliability, and ensure long-term durability in critical power cable applications.
What is a Thermoplastic Semicon Jacketing Compound?
A thermoplastic semicon jacketing compound is a specialised conductive material applied over the outer sheath of MV, HV, and EHV cables. Its primary purpose is to create a conductive layer that enables sheath testing during production, installation, and throughout the cable’s service life.
To understand its importance, it is essential to distinguish between:
- Insulation – prevents electrical current flow
- Shielding – controls electrical fields within the cable
- Jacketing – protects the cable from mechanical, chemical, and environmental stress
A semicon jacket for power cables combines protective jacketing with controlled conductivity. This conductive sheath enables technicians to detect defects, localise faults, and verify sheath integrity across the entire cable length. Without this outer conductive layer, identifying sheath failures becomes significantly more difficult, increasing maintenance risks and operational costs.

The compound flows smoothly during extrusion, enabling stable production speeds and excellent surface quality. - Sheath integrity across the product lifecycle
From manufacturing to installation and long-term service, the compound maintains exceptional mechanical stability and adhesion. - Reliable defect detection and troubleshooting
The conductive layer allows for continuous sheath testing, making it easy to pinpoint faults or damage. - Versatility across voltage classes
Suitable for MV, HV, and EHV cable designs, making it an industry-wide adaptable material.
How It Works: Enhancing Cable Integrity and Safety
The outer conductive layer formed by a semicon jacket for power cables plays a major role in system reliability. By providing a uniform conductivity path along the cable sheath, technicians can perform:
- Voltage withstand tests
- Sheath integrity tests during installation
- Fault localisation during service
These tests help detect cuts, pinholes, abrasions, or ageing-related defects early. Early detection prevents catastrophic failures such as insulation breakdown, flashovers, or moisture‑driven corrosion. Ultimately, this reduces downtime and ensures safety across the network.
Applications Across Voltage Levels
- Medium Voltage (MV): Used extensively in industrial plants and utility networks where reliability is essential.
- High Voltage (HV): Ideal for transmission lines connecting substations, where sheath monitoring is crucial.
- Extra‑High Voltage (EHV): Critical for long-distance and high-capacity grids where the cost of failure is extremely high.
In all these applications, our ESCONTEK SP-PESC-566 compound enables continuous monitoring and preventive maintenance especially beneficial in buried or difficult-to-access installations.
Benefits of Using SHAKUN ESCONTEK SP-PESC-566
Our ESCONTEK SP-PESC-566 provides several operational advantages:
- Higher safety and reduced maintenance:
The compound’s conductive and durable nature enhances operational safety while significantly reducing the need for frequent maintenance checks and repairs. - Improved fault localisation accuracy:
The uniform conductivity of the semicon jacket enables precise detection of defects or damage along the cable, allowing for quicker and more accurate fault localisation. - Better production efficiency due to smooth extrusion:
Its excellent extrusion characteristics result in consistent surface quality and stable processing, leading to increased efficiency during cable manufacturing. - Longer cable service life in harsh conditions:
With strong resistance to environmental and mechanical stress, the compound helps extend the operational lifespan of cables even in aggressive or demanding field conditions. - Minimised risk of unexpected failures or outages:
By supporting early defect detection and continuous sheath monitoring, the compound reduces the likelihood of sudden cable failures or costly power outages.
Our formulation ensures stable conductivity, mechanical strength, and resistance to environmental stresses.
Choosing the Right Semiconducting Jacketing Compound
When selecting a semicon jacket for power cables, we recommend evaluating:
- Conductivity consistency
- Ease of extrusion and processing stability
- Mechanical robustness against bending, pulling, or compression
- Resistance to chemicals, moisture, and temperature variations
- Uniform dispersion of conductive medium
Uniform conductive distribution is especially important, as it determines the accuracy and reliability of sheath integrity testing.
