Nā Nūhou Huahana

ʻO nā uaea mea hana i kū ʻole i nā lula e hiki ai ke nalowale ka hōʻailona, ​​​​ka hāʻule ʻana o nā lako, a me nā pōʻino palekana.

Hōʻike ka ʻikepili ʻoihana he 80% o nā mea hoʻonohonoho kū ʻole i nā lula e ʻike i nā pilikia i loko o 18 mau mahina.

E aʻo i nā hopena maoli o ka haʻalele ʻana i nā koi EN 50288-7, IEC 60332, a i ʻole NEC - a no ke aha e pale ai ka mālama ʻana i kāu mea kanu.

ʻO ke koho ʻana i nā kaula mea hana he nui nā pālua e pono ai ka hoʻoholo ʻana i ka helu o nā pālua (1-100+), ka nui o ke alakaʻi (18-24 AWG / 0.5-2.5mm²), ke ʻano pale (foil/braid/composite), a me ka mea ʻaʻahu (PVC/LSZH/PUR).

Uhi kēia alakaʻi i ka mālama ʻana iā EN 50288-7 a me kahi ʻōnaehana koho ʻanuʻu no nā hōʻailona analog a me kikohoʻe.

ʻO EN 50288-7 ke kūlana ʻEulopa no nā kaula hana a me nā kaula kaohi, e kuhikuhi ana i nā ʻano uila (impedance, capacitance, attenuation), nā waiwai mechanical, flame retardancy, a me nā helu mahana.

Pono nā mea kūʻai e hōʻoia i ka kūlike no ka māka CE a me nā kikoʻī o ka papahana.

E aʻo i nā pono nui a me ka papa inoa koho.

ʻO ke koho ʻana ma waena o ka twisted pair (crosstalk reduction), coaxial (high-frequency), a me BS5308 (ʻaila a me ke kinoea spec) e pili ana i kāu ʻano hōʻailona, ​​​​ka mamao, a me ke kaiapuni.

ʻOi aku ka maikaʻi o ka twisted pair no 4-20mA a me RS485. Coaxial no ke alapine kiʻekiʻe a me ke wikiō.

Hoʻohui ʻo BS5308 i ka pale mechanical a me ka helu IS no nā hale hana petrochemical.

E aʻo i nā koi a me nā ʻokoʻa.

Pono nā kaula palekana kūloko he uliuli māmā (RAL 5015) e like me IEC 60079-14 no ka ʻike ʻana i nā wahi weliweli.

ʻAe kēia code kala i koi ʻia i nā mea uila e hoʻokaʻawale koke i nā kaapuni IS mai nā kaula mana ʻaʻole IS, e pale ana i ka pili ulia pōpilikia o ka ikehu weliweli.

E aʻo i nā koi a me nā ʻokoʻa.

ʻO ka pane pololei: ʻAʻole.

E aʻo i nā koi a me nā ʻokoʻa.

ʻAe, e like me IEC 60079-14, pono i nā kaula palekana maoli ke loaʻa kahi ʻāpana waho polū māmā (RAL 5015) no ka ʻike ʻana i nā wahi weliweli.

ʻO kēia code kala i koi ʻia e ʻae i ka ʻike maka koke ʻana o nā kaapuni IS, e pale ana i ka hoʻopili ulia pōpilikia o ka mana ʻaʻole IS.

Aia nā ʻokoʻa palena no nā uaea liʻiliʻi loa a me nā mea i hoʻonohonoho ʻia.

E aʻo i nā koi a me nā ʻokoʻa.

Hoʻohui kahi kaula SWA (Steel Wire Armour) palekana maoli i ka palena ikehu (IS) me ka pale mechanical (pale kila). Ke kūpaʻa nei i ka ʻānai a hiki i ka 4,000 N/10cm, ka pale ʻana i nā rodent/vermin, a me ka ikaika tensile kiʻekiʻe no nā hoʻonohonoho wahi weliweli. Mālama ka ʻūpā LSZH polū māmā i ka hoʻokō ʻana i ka IS ʻoiai ʻo ka pale kaua e hoʻohui i ka lōʻihi.

E aʻo i nā koi a me nā ʻokoʻa.

Hoʻohui kahi uwea hoʻāla ahi palekana maoli i ka palena ikehu (pale i ka hoʻā ʻana) me ka pono o ke kaapuni (mālama i ka hana i ka wā o ke ahi).

Ua hōʻoia ʻia no nā wahi weliweli (Zone 0/1/2) me nā helu e like me FE180 (180 mau minuke ola ahi) a me ka uhi ʻana o LSZH.

E aʻo pehea e ʻike ai nā uaea ahi IS i nā ahi me ka ʻole o ke kumu.

ʻO nā kaula palekana kūloko he uliuli (RAL 5015) e like me IEC 60079-14 no ka ʻike maka koke ʻana i nā wahi weliweli. ʻO kēia code kala i koi ʻia e hiki ai i nā mea uila ke hoʻokaʻawale koke i nā kaapuni IS mai nā kaula mana ʻaʻole IS—e pale ana i ka pili ʻana o ka ikehu weliweli. E aʻo i ke kūlana maʻamau, nā ʻokoʻa, a me nā pae koho.
