There are several types of insulated safety shoes for auxiliary safety equipment, including 20kV, 6kV, and 5kV, according to the voltage range. When using them, they must be selected according to the operating range. Insulated shoes should be regularly inspected and maintained. If they are damp or severely worn, they cannot provide protection. Rubber synthetic sole. Indian buffalo leather upper, tough and durable, waterproof and oil resistant. Pigskin lining, wear-resistant and breathable. EVA insole, sweat absorbing and breathable. Anti impact insulation (6-10kv). Product compliance standard: LD50-1994? AN-I level electrical insulation standard: GB12011-2000 Remarks: 1. This product is an electrical safety protective shoe suitable for high-voltage electrical operations below 10 kV. It has a certain protective effect on acid alkali oil and can also be used as safety protective equipment for other types of work. This product is produced according to the GB12011-2000 national insulation standard. 2. During the wearing process of this product, sharp objects should be avoided. Once sharp objects pierce the insulation sole or the anti slip pattern on the sole is smoothed out, it will no longer have insulation performance. 3. The insulation performance standard of this product: Increase the voltage from zero to 75% of the 6KV voltage value at a speed of 1KVIS, and then increase it to 6KV at a speed of 100VIS. It should be maintained for 1 minute and accurate to 0.1mA. If the product is not qualified, the company is responsible for replacement. 4. When wearing insulated leather shoes, it is necessary to avoid contact with sharp objects. It is strictly prohibited to nail the soles of the shoes with iron to prevent the insulation performance from decreasing. After wearing them for a period of time, preventive electrical insulation tests should be conducted to ensure safety. 5. Suitable for job protection in industries such as electricity, postal and telecommunications, and enterprise electricians. Product quantity unlimited production packaging instructions 12 pairs/box 6. Size: 35-45 anti impact safety shoes KLS anti impact safety shoes newly developed rib reinforcement steel head strength far exceeds the highest domestic standard AN1, making it more safe Fully in compliance with the heavy duty standard CNS6863 Z2029 Class H. Imported steel from Germany, with elevated and widened steel heads, resistant to impact and pressure, surpassing domestic AN1 standards. It has undergone anodizing, heat treatment, paint baking, and other rust prevention treatments, making it not only more spacious and comfortable to wear, but also more secure. Impact resistance: In accordance with the CNS heavy work standard (H) of 23kg/45cm. 200-250 joules) anti-static safety shoes adopt a unique anti-static formula, significantly reducing the resistance of the anti-static safety shoes to 10's 7th to 10's 9th ohms, and conductive shoes can reach 10's 3rd to 10's 5th ohms. Anti static, efficient and long-lasting, non-toxic, RoHS compliant, suitable for compatibility with polyurethane, and does not affect the processing and usage performance of the product
