<h2>10. Frequently Asked Questions<\/h2>\n\n <div class=\"faq-item\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n <p class=\"faq-question\" itemprop=\"name\">What does the designation NSSHOEU mean?<\/p>\n <div class=\"faq-answer\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n <p itemprop=\"text\">The designation follows German cable nomenclature per DIN VDE standards: N = standard type, SS = special rubber with reinforced protection, H = halogen-free or heavy-duty compound, O = without concentric conductor, E = copper screening element, U = rubber outer sheath. The “J” suffix (NSSHOEU-J) indicates inclusion of a green\/yellow protective earth conductor, while “O” suffix (NSSHOEU-O) indicates absence of protective earth conductor.<\/p>\n <\/div>\n <\/div>\n\n <div class=\"faq-item\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n <p class=\"faq-question\" itemprop=\"name\">What is the maximum submersible depth for PROTOMONT NSSHOEU cables?<\/p>\n <div class=\"faq-answer\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n <p itemprop=\"text\">PROTOMONT NSSHOEU cables can be permanently submerged in water up to 2000 meters depth at temperatures up to 40\u00b0C. This exceptional depth rating makes them suitable for deep-water mining, pump applications, and industrial water processing systems. At higher water temperatures, reduced service life should be expected.<\/p>\n <\/div>\n <\/div>\n\n <div class=\"faq-item\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n <p class=\"faq-question\" itemprop=\"name\">Can NSSHOEU cables be used in explosive atmospheres?<\/p>\n <div class=\"faq-answer\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n <p itemprop=\"text\">Yes, PROTOMONT NSSHOEU cables are suitable for use in explosion-hazard areas, subject to local regulations. The cables hold MA-China certification for coal mine safety and MSHA P-189-3 approval for US mining applications. Installation must comply with applicable explosion protection standards (ATEX, IECEx) and be performed by qualified personnel.<\/p>\n <\/div>\n <\/div>\n\n <div class=\"faq-item\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n <p class=\"faq-question\" itemprop=\"name\">What is the difference between NSSHOEU-O and NSSHOEU-J?<\/p>\n <div class=\"faq-answer\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n <p itemprop=\"text\">NSSHOEU-J cables include a green\/yellow protective earth (PE) conductor, making them suitable for applications requiring equipment earthing through the cable. NSSHOEU-O cables do not include this protective earth conductor and are used where earthing is provided through other means or where an earth conductor is not required.<\/p>\n <\/div>\n <\/div>\n\n <div class=\"faq-item\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n <p class=\"faq-question\" itemprop=\"name\">What is the temperature range for flexible operation?<\/p>\n <div class=\"faq-answer\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n <p itemprop=\"text\">For fully flexible operation (continuous bending and movement), the ambient temperature range is -25\u00b0C to +60\u00b0C. For fixed installations without movement, the cable can operate in ambient temperatures from -40\u00b0C to +80\u00b0C. The maximum conductor operating temperature is 90\u00b0C for both applications.<\/p>\n <\/div>\n <\/div>\n\n <div class=\"faq-item\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n <p class=\"faq-question\" itemprop=\"name\">Are NSSHOEU cables resistant to oils and chemicals?<\/p>\n <div class=\"faq-answer\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n <p itemprop=\"text\">Yes, the outer sheath compound (5GM5 per DIN EN 50363) provides excellent resistance to oils and fats per DIN EN 60811-404. The cable also resists many chemicals encountered in mining and industrial environments. However, for aggressive chemicals or unusual substances, resistance properties should be tested prior to installation.<\/p>\n <\/div>\n <\/div>\n\n <div class=\"faq-item\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n <p class=\"faq-question\" itemprop=\"name\">What sizes are available for PROTOMONT NSSHOEU cables?<\/p>\n <div class=\"faq-answer\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n <p itemprop=\"text\">PROTOMONT NSSHOEU cables are available in a comprehensive range of configurations.
