Product Description
Overhead Line Insulation Sleeve (OLIS)
Overhead Line Insulation Sleeve (OLIS) is a highly tensile stretchable rubber element which used as a jacket around the electric power transmission line of the overhead cranes and wide range of other industrial machineries. This protection unit gives protection against shot circuit to prevent machine breakdown and accidents due to electricity. Top quality synthetic polymers are used for the manufacturing of this sleeve which makes it highly durable and resistant to bends.

High Dielectric Strength for Enhanced Protection
With a dielectric strength of 18 kV/mm, OLIS provides reliable electrical insulation and minimizes the risk of leakage currents or short circuits. The sleeves' breakdown voltage exceeding 20 kV/mm ensures maximum safety, even under demanding electrical loads common in utility and industrial environments.
Weatherproof and UV Resistant for Longevity
OLIS sleeves are constructed from UV-stabilized materials, offering resistance against solar exposure, moisture, and challenging outdoor conditions. Their weatherproof, anti-tracking characteristics make them suitable for long-term field installations, preserving their insulating properties for 10-15 years.
Installation Versatility and Customization Options
Available in various widths, thicknesses, and colors, these sleeves support customized lengths and diameters as per the conductor size. Installation can be performed manually during routine shutdowns or on live lines using suitable tools, ensuring flexibility across multiple project requirements.
FAQ's of Overhead Line Insulation Sleeve (OLIS):
Q: How do I install the Overhead Line Insulation Sleeve (OLIS) on overhead conductors?
A: OLIS installation involves slipping the sleeve over the exposed conductors or jumpers, either manually during a power shutdown or on live lines with specialized tools. It is crucial to ensure the sleeve fits snugly around the conductor and is positioned securely as per installation guidelines for optimal insulation.Q: What benefits does OLIS provide for overhead power lines?
A: OLIS protects overhead conductors from environmental exposure, bird-related faults, and accidental contacts. It delivers high dielectric and mechanical strength, is self-extinguishing, weatherproof, and UV resistant, significantly increasing safety and extending the service life of power lines.Q: When should OLIS be replaced or checked for maintenance?
A: OLIS sleeves have a life expectancy of 10-15 years outdoors but should be inspected during routine maintenance for signs of wear, UV degradation, or mechanical damage. Replacement is recommended if physical defects or loss of insulating properties are detected.Q: Where should OLIS be stored before installation?
A: Store OLIS sleeves in a dry, shaded area to prevent moisture absorption and UV exposure. Proper storage ensures the material retains its mechanical and insulation properties prior to use.Q: What materials and specifications are available for OLIS?
A: OLIS is available in premium PVC or high-density polymer, comes in widths from 25 mm to 100 mm, thicknesses from 2 mm to 5 mm, and supports rated voltages from 11 kV to 33 kV. Color and length can be customized based on application requirements.Q: How does OLIS contribute to electrical safety and performance?
A: By providing insulation with a dielectric strength of 18 kV/mm and a breakdown voltage above 20 kV/mm, OLIS minimizes risks of electrical leakage, arc faults, and enhances network reliability. Its anti-tracking and flame-retardant features further improve operational safety.Tell us about your requirement
