When you need a compact, field-proven Porcelain Shackle Insulator for overhead distribution, MNC Electrical’s shackle type insulator range is built for reliable insulation + mechanical fixing at terminals, turns, and branch nodes. From ANSI spool styles (53 series) to ED-series butterfly designs, each Porcelain Shackle Insulator is designed for stable outdoor performance and flexible mounting (horizontal/vertical) so installers can use the same shackle type insulator across multiple pole structures and line layouts.
MNC Electrical offers multiple Porcelain Shackle Insulator sizes, letting you match conductor load, space constraints, and fittings—while staying within the same shackle type insulator product family. Typical size coverage across the lineup includes:
ED-4: H 50 mm, D 60 mm (compact Porcelain Shackle Insulator)
53-1: H 54 mm, D 57 mm (shackle type insulator for lighter duty)
1617 / ED-3: H 65 mm, D 76/70 mm (mid-size Porcelain Shackle Insulator)
ED-2 / 53-2: H 75–76 mm, D 80–79 mm (general-purpose shackle type insulator)
ED-1: H 90 mm, D 100 mm (heavy-duty Porcelain Shackle Insulator)
Each Porcelain Shackle Insulator is specified for low-voltage networks (≤1 kV on key models) and focuses on dependable flashover performance plus mechanical strength—exactly what a shackle type insulator must deliver on terminal/tension/turning points. Examples across MNC products include:
Power-frequency flashover (dry): 14–30 kV for Porcelain Shackle Insulator options
Power-frequency flashover (wet): 8–17 kV depending on shackle type insulator model
Mechanical failing/breaking load: ~9–13.6 kN across the Porcelain Shackle Insulator range
Lightweight handling: about 0.20–0.75 kg per shackle type insulator model
MNC Electrical organizes its Porcelain Shackle Insulator selection into practical shackle type insulator types for common line tasks:
ANSI spool / reel types (53-1, 53-2): suited for fixing and turning conductors, with design features for outdoor stability
ED-series butterfly types (ED-1/2/3/4): compact-to-heavy-duty Porcelain Shackle Insulator choices, supporting horizontal/vertical installation and OEM customization (e.g., glaze color)
1617 type: a widely used shackle type insulator size option within the same product category
If you’re sourcing a Porcelain Shackle Insulator for terminals, angles, or branch points, MNC Electrical’s shackle type insulator lineup (53-1 / 53-2 / 1617 / ED-1 / ED-2 / ED-3 / ED-4) provides size coverage, electrical margins, and mechanical ratings to fit most low-voltage distribution builds.
