132 kv Single Tension Insulators Hardware Fittings

132 kV Single Tension Insulator Hardware Fitting is a specialized component used in high-voltage transmission lines to manage unidirectional mechanical loads while ensuring electrical insulation. It is typically deployed at points where conductors terminate or change direction, such as dead-end towers or moderate-angle locations.

Key Components and Functionality

Voltage Rating (132 kV):
Designed for high-voltage applications, ensuring sufficient electrical insulation to prevent flashovers and leakage currents.
Smooth, rounded edges on fittings minimize corona discharge and ionization risks.


Single Tension Design:
Unidirectional Load Handling: Manages axial tension from conductors at termination points (dead-end towers) or moderate-angle towers.
Simpler Configuration: Uses a single insulator string (vs. double tension’s dual strings), reducing hardware complexity and cost.
Mechanical Strength: Rated for typical loads (e.g., 50–120 kN), depending on span length, conductor weight, and environmental factors (wind/ice).


Hardware Components:
Tension Clamp: Secures the conductor and transfers mechanical load to the insulator string.
Ball-and-Socket or Clevis-Tongue Links: Connect the insulator to the tower and conductor, allowing articulation to avoid stress concentrations.
Yoke Plate/Anchor: Attaches the insulator string to the tower structure.


Glass Insulators:

High Durability: Resistant to UV, pollution, and temperature fluctuations. Mechanical strength typically ranges from 70 kN to 160 kN.
Visual Inspection: Cracks or defects are easily detectable, ensuring timely maintenance.


Applications
Dead-End Towers: Terminates conductors at line endpoints or substation entrances.
Moderate-Angle Towers: Handles directional changes in transmission lines (e.g., 15°–30° angles).
River Crossings or Short Spans: Used where moderate tension loads are expected.
Retrofitting Older Lines: Upgrades systems with glass insulators for improved reliability and longevity.
