The key to look at the temperature! Slight heating is a normal phenomenon of current transmission, but abnormally high temperatures are a hidden crisis. Overload, poor contact or aging may lead to wire harness temperature soaring, which may affect the life of the equipment, or cause fire accidents.<\/h6><div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><h6 class=\"wp-block-heading has-ast-global-color-3-color has-text-color has-link-color wp-elements-5d820040e92c175dc255ac1782196b80\" id=\"h-wiring-harnesses-made-of-different-materials-have-different-temperature-resistance-ordinary-pvc-wire-70-on-the-danger-and-silicone-wire-can-withstand-high-temperatures-of-200-automotive-wiring-harnesses-should-usually-be-able-to-withstand-105-c-and-household-wires-should-not-exceed-50-c-ambient-temperature\" style=\"font-size:17px;line-height:1.7\">Wiring harnesses made of different materials have different temperature resistance: ordinary PVC wire 70 \u2103 on the danger, and silicone wire can withstand high temperatures of 200 \u2103. Automotive wiring harnesses should usually be able to withstand 105 \u00b0 C, and household wires should not exceed 50 \u00b0 C ambient temperature.<\/h6><div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><h6 class=\"wp-block-heading has-ast-global-color-3-color has-text-color has-link-color wp-elements-94ac3cc2fa250a032a637ba5e3087500\" id=\"h-how-to-judge-hand-measured-60-is-the-safety-threshold-more-than-that-need-to-be-vigilant-professional-testing-suggests-the-use-of-infrared-thermometer-accurate-and-safe-prevention-is-better-than-cure-proper-wiring-regular-checking-and-load-matching-make-your-electricity-safer\" style=\"font-size:17px;line-height:1.7\">How to judge?
