Nnwale nchedo mbata (IP)

Ọ na-ekpebi ma ìhè ahụ ọ ga-echebe akụkụ ọrụ site na mmiri, uzuzu, ma ọ bụ ihe siri ike, na-eme ka ngwaahịa ahụ dị nchebe na eletriki ma na-adịte aka. Nnwale IP na-enye ọkọlọtọ nnwale a na-emegharị iji tụnyere nchekwa ogige. Kedu ka ọkwa IP si dị? Nọmba mbụ na ọkwa IP na-anọchite anya ọkwa nchebe megide ihe siri ike site na aka ruo uzuzu, ọnụọgụ nke abụọ na ọkwa IP na-anọchite anya ọkwa nchebe megide mmiri dị ọcha site na 1mm nke mmiri ozuzo ruo na mikpuo nwa oge ruo 1m.

Were IP65 dịka ọmụmaatụ, "6" pụtara enweghị uzuzu ịbanye, "5" pụtara nchekwa megide jet mmiri site n'akụkụ ọ bụla. Nnwale IP65 chọrọ nrụgide 30kPa n'ebe dị anya nke 3m, yana olu mmiri 12.5 lita kwa nkeji, oge nnwale bụ nkeji 1 kwa square mita maka opekata mpe nkeji 3. Maka ọtụtụ ọkụ dị n'èzí, IP65 dị mma.

Ụfọdụ mpaghara mmiri ozuzo chọrọ IP66, ihe "6" e ji echebe ya pụọ ​​na jet mmiri dị ike na oke osimiri. Nnwale IP66 chọrọ nrụgide 100kPa n'ebe dị anya nke 3m, yana olu mmiri 100 lita kwa nkeji, oge nnwale bụ 1 nkeji kwa square mita maka opekata mpe nkeji atọ.

Nnwale nchedo mmetụta (IK)
