Cable Connectors
A poor electrical connection causes about 30% of an electrical accident.
Electrical Connectors, detecting overheat
Change color when detecting overheat!

» Visual inspection using overheat detection by insulation cap (EYECAP) without a thermal camera
» Visual inspection for complete connection of cable and lug by Terminal Tab
» Visual inspection for crimping status on cable by insulation capPreventive maintenance applications reducing the problems caused by overheat in the electricity distribution network provides un-interrupted energy and less loss on material by monitoring the electrical cables and connection points

Degradation and the risks
When a polymer material such as an electric wire is heated, the pyrolysis of the material starts, decomposition starts at 90℃, and it generates the gas. Thereafter, heat accumulation proceeds inside the connecting material, and as the temperature of the material increases, it creates smoke. If the temperature continues to rise and exceeds the ignition point, it may generate the flame to spread to a fire.
; Eyecap is made of silicone, no melting, fire-retardant, no generating harmful gas.

What is REACH?
It stands for Registration, Evaluation, Authorization, and Restriction of Chemicals. European New Chemical Substance Management System and EU Regulation of all chemical substances handled more than 1 ton per year in the EU. i.e., chemical strengthening is spreading all over the world including the US and China.
; EyeCap is certified by REACH

Risk of PVC Material
It is prohibited to use a substance of high-risk concern, regulated by the REACH system as European environment regulation system (SVHC: Substance of Very High Concern, the hazardous substance of concern, the standard is 0.1% or less)
The trend is to restrict its use in special environments such as semiconductors and display production lines since it is classified as human “endocrine disruptor” (environmental hormone substance); Made of silicone, Eyecap doesn’t have SVHC

Arc Generation and the Risks
Arc is a flash discharge phenomenon that occurs in an insulator and usually causes the electrode to burn out. The generation of an arc varies from an instant to a long time, and the magnitude of the energizing current and the arc duration are the main factors of the fire. Also, arc defects can occur at temperatures 1,000℃ or above even with small currents. Thus, an arc can be a direct cause of fire or it may cause a fire through insulator deterioration flash.
; By complete connection of Cable and Lug, there is no chance of Arc generation.
