1617 Spool Insulator — IEC Standard Brown Glaze Porcelain Insulator
The 1617 spool insulator is a brown-glazed porcelain insulator manufactured in compliance with IEC Standard requirements for overhead line insulators.
Also known as a shackle insulator, this spool-type insulator is designed for low-voltage distribution lines, providing reliable insulation and conductor support at line terminals, tension poles, and corner poles.
The 1617 model features a compact cylindrical body with circumferential wire grooves that secure conductors via soft-bending tie wires. It can be mounted in either vertical or horizontal positions, making it versatile for various pole-top configurations.

Dimensions and Design
The 1617 spool insulator has a diameter of 76 mm and a height of 65 mm. The compact design allows for efficient stacking and transportation, with a net weight of approximately 0.40 kg per unit. The brown glaze finish provides enhanced weathering resistance and UV stability for outdoor overhead line applications.
Mechanical Performance
With a transverse strength of 9.1 kN, the 1617 spool insulator is engineered to withstand the mechanical loads encountered in low-voltage distribution networks, including conductor tension at terminal poles and sharp turns. This mechanical rating ensures reliable performance under continuous tensile stress.
Electrical Characteristics
The 1617 insulator delivers dependable electrical insulation performance:
- Low Frequency Dry Flashover Voltage: 20 kV
- Low Frequency Wet Flashover Voltage, Vertical: 9 kV
- Low Frequency Wet Flashover Voltage, Horizontal: 10 kV
These ratings confirm the insulator’s suitability for low-voltage overhead distribution systems. The wet flashover performance in both vertical and horizontal mounting orientations provides design flexibility for utility engineers.
Standards and Compliance
The 1617 spool insulator is manufactured to comply with IEC Standard requirements for overhead line insulators. IEC standards are published by the International Electrotechnical Commission (IEC). Relevant standards and publications can be found through the IEC Webstore.

Applications
The 1617 spool insulator is primarily used in low-voltage overhead distribution lines for:
- Terminal poles — supporting conductors at the end of distribution runs
- Tension poles — managing mechanical loads at line angles
- Corner poles — providing insulation at sharp direction changes
- Secondary racks — dead-ending or supporting secondary voltage conductors
Spool insulators are mounted either vertically or horizontally and are secured using spool bolts, clevises, or secondary racks. The conductor is tied into the circumferential grooves using soft-bending wire, ensuring a secure and insulated connection.
Installation Notes
- The insulator is mounted axially, with loading applied to the circumferential grooves.
- Conductors are secured in the grooves using soft-bending tie wires.
- The insulator can be bolted to the cross-arm of the pole.
- Both vertical and horizontal mounting positions are supported.
