Product Type: FXB-24-70YQ-680mm
End Fittings: Ball & Y
Height(mm): 450 10
Min Dry Arcing Distance(mm): 280
Min Creepage Distance(mm): 680
Diameter of the rod(mm): 18
Number of sheds: 5
Sheds of diameter(mm): 120
Specified Mechanical Load(SML): 70kN
Routine Test Load (RTL): 35kN
Rated Voltage(kV): 24
Lightning Impulse Withstand Voltage(kV): 230
Power Frequency Withstand Voltage(kV): 75
Product Parts Display:
① End Fitting type: Ball
Forged steel and hot dip galvanized,minimum thinkness of the galvanization:86µm
② The thickness of silicone rubber housing is more than 3mm,it is in accordance with IEC standard.
③ The acid-resistance,high terperature-resistance core rod use the materials epoxy & glassfiber.
④ End fitting type: Y Type
Forged steel and hot dip galvanized, minimum thinkness of the galvanization:86µm
Production Display:
Main Features:
1. Rated Voltage & Mechanical Strength:
Rated System Voltage:24kV (typically used in distribution networks).
Mechanical Load Capacity:70kN (approx. 7,000 kgf), suitable for moderate mechanical stresses.
2. Composite Design:
Core:Fiberglass reinforced epoxy resin (high tensile strength, corrosion-resistant).
Weathersheds:Silicone rubber housing with five grey sheds (optimized for pollution resistance and hydrophobicity).
Shed Profile:5-shed design to enhance creepage distance and prevent flashover in wet or contaminated environments.
3. Hardware (End Fittings):
Ball (Ball Head) & Y-Type Socket (Clevis) Connection:
Ball Head (Male End):Standard spherical ball conforming to IEC 60120 or ANSI standards, typically attached to the tower cross-arm.
Y-Type Socket (Clevis, Female End): Fork-shaped clevis for connection to conductor fittings(e.g., suspension clamps or links).
Material: Hot-dip galvanized steel or forged alloy for corrosion resistance.
Connection Scenarios:
1. Suspension Applications:
The ball end is fixed to a tower suspension eyelet (cross-arm), while the Y-clevis connects to the conductor’s suspension clamp or damper assembly.
Commonly used in distribution lines where flexibility in hardware alignment is required.
2. Dead-End/Tension Applications:
If bidirectional load-bearing is needed, two insulators may be paired (back-to-back) with Y-clevis ends linked via a thimble or shackle.
3. Substation Use:
The ball-Y combo allows easy swiveling to accommodate thermal expansion/contraction of busbars or jumpers.
Standards Compliance:
IEC 61109 / ANSI C29.11 (composite insulators).
Hardware dimensions follow IEC 60120 (ball/clevis) or utility-specific specifications.
Advantages:
Lightweight compared to porcelain, reducing tower load.
UV-resistant silicone sheds for long-term outdoor performance.
-Ball-Y connection ensures 360° rotation, mitigating torsional stress from wind or conductor movement.
