Forged Suspension Clamp
The ZTT forged suspension clamp is manufactured from forged aluminium alloy, giving half the weight and double the mechanical strength compared with conventional cast suspension clamps. Forging also reduces material use and carbon emissions in production, and the resulting body is highly wear resistant. The design is covered by ZTT / Jiangdong intellectual property rights and has passed the national appraisal for forged suspension and self-lock spacer products.
Features & Characteristics
- ▪Half weight, double strength versus conventional cast suspension clamps.
- ▪Energy-saving, resource-saving and environment-friendly — lower carbon emissions in production.
- ▪Own intellectual property rights (national appraisal passed).
- ▪Forged body — wear-resistant and dimensionally accurate.
Applications
- ▪Suspension of conductors on high-voltage, EHV and UHV overhead lines.
- ▪Weight-critical projects such as long-span river crossings and UHV lines.
- ▪OPGW / OPPC suspension where light and strong hardware is required.
