Kabelning suv o'tkazmaydigan darajasi

IEC 60529 va QB/T 1898 standartlariga muvofiq, ulanish kabellarining suv o'tkazmasligi quyidagi darajalarga bo'linishi mumkin:

IPX-0 suv o'tkazmaydigan himoyaga ega emas va mahsulot uchun suv o'tkazmaydigan himoya talablari yo'q.

IPX-1 talablari: Oddiy ish sharoitida kabel 10 daqiqa davomida suv oqishsiz 3-5 mm / min yomg'irga teng suv o'tkazmaydigan himoyani ta'minlay oladi.

IPX-2 talablari: Bu daraja asosan IPX-1 bilan bir xil, ammo u suv oqishsiz barcha yo'nalishlarda 15 daraja suv o'tkazmaydigan sinovdan o'tishi mumkin.

IPX-3 talablari: 60 graduslik burchakli chayqaladigan suvdan himoya qilish, 2-5 daqiqa davomida 10 litr / sekund oqim tezligini va suv oqishiga qarshi 80-100n / m bosimli suv o'tkazmaydigan himoyani ta'minlaydi.

IPX-4 talablari: Bu daraja asosan IPX-3 bilan bir xil, ammo u har tomonlama va burchakli chayqalish va suv oqishidan suv o'tkazmaydigan himoyani ta'minlaydi.

IPX-5 talablari: Barcha yo'nalish va burchaklardan suv o'tkazmaydigan himoya, 2-3 daqiqa davomida 12,5 litr / sek oqim tezligini va suv oqishiga qarshi 30 n / m bosimli suv o'tkazmaydigan himoyani ta'minlaydi.

IPX-6 talablari: Katta to'lqinlardan suv o'tkazmaydigan himoya, suv ostida 3 metr chuqurlikda 2-3 daqiqa davom etishi mumkin, oqim tezligi 100 litr / min, bosim 100 n / m suv o'tkazmaydigan.

IPX-7 talablari: 1 metr suv ostida 30 daqiqa davomida sizib chiqmasdan namlash mumkin.

IPX-8 talablari: to'liq suv o'tkazmaydigan, suvda uzoq vaqt davomida oqmasdan foydalanish mumkin.

IP69K talablari: EN60529 va DIN40050-9da belgilangan issiq bug'ni yuvish sinoviga bardosh bera oladi.

This provides protection against a water pressure of 100 bar (1450psi) and a temperature of 80ºC. Pressure is applied directly to the sensor in 30-degree increments (0, 30, 60 and 90 degrees) for 30 seconds at each angle for a total of 120 seconds (2 minutes), preventing the ingress of water.

For different waterproof levels, international and domestic standards have corresponding waterproof test methods and specifications, such as GB 4208-2008/IEC 60529-2001 "Enclosure Protection Level (IP Code)" standard requirements. Nowadays, most of the cable manufacturers are still in the initial stage of understanding the waterproof of the cable, but a few professional manufacturers of waterproof cable have made corresponding standards and applications for the waterproof level of the cable.
