• Type: Standard profile Toughened Suspension Type
• Rated mechanical load: 160kn (approx. 16 tons)
• Purpose: Widely applicable as insulation support for medium and high voltage transmission lines and substation equipment under various climatic conditions.

• Compliance: IEC60383-1:1993, MOD / GB/T1001.1
• Connection structure: GB/T4056-2008 (IEC60120:1984, MOD) and BS 3288 part III.
• Locking pin: W-pin or R-pin (W-pin is standard for U160BS).

Main Elements:

• Dielectric made of toughened glass with specific properties for various environments.
• Hot-dip galvanized nodular or ductile malleable cast iron cap.
• Hot-dip galvanized forged steel pin.
• Aluminous cement assembly to withstand thermomechanical efforts.
• Stainless steel or phosphor bronze locking device (split pin).
• Optional anti-corrosion zinc sleeve for heavy pollution areas.

Under long-term electrical stress, contaminants can trigger local arcs. Our design provides sufficient creep distance to disperse electric field strength, reducing discharge risk and extending product life.
