What is a Surge Protective Device (SPD)?
A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from
• Dual wall insulation.
• Electron beam cross-linked
• Excellent resistance to U.V, oil, greases, oxygen and ozone
• Excellent resistance to abrasion
• Halogen free, flame retardant, low toxicity
• Excellent flexibility and stripping performance
• High Voltage and Current carrying capacity
• TUV, CE, ISO approved
