Maemong a matla a phahameng a kang matla a macha, boenjiniere ba motlakase le taolo ea indasteri, ho koahela li-terminal ke ts'ebetso ea mantlha ea ho netefatsa khokahano e sireletsehileng ea motlakase. Lipalo-palo li bontša hore 35% ea mollo oa motlakase o bakoa ke likhokahano tse hlephileng kapa tse fokolang tsa li-terminal. E le paramethara ea bohlokoa ea ts'ebetso ea ho koahela li-terminal, karolelano ea khatello e khetholla ka ho toba matla a mechini le ho tsamaisa motlakase ha likhokahano. Sengoloa sena se hlalosa ka botlalo mefuta e metle ea karolelano ea khatello, foromo ea lipalo, lintlha tse susumetsang le lintlha tsa bohlokoa tsa ts'ebetso e sebetsang bakeng sa ho koahela li-terminal ka matla a phahameng, tse ka sebelisoang hang-hang.
I. Tekanyo ea Khatello ke eng? Utloisisa tlhaloso ea eona ea mantlha pele
Karolelano ea khatello (e tsejoang hape e le sekhahla sa khatello kapa sekhahla sa ho hatelloa) e lekanya karolelano ea phetoho ea sebaka se tšelang likarolo tsa mokhanni pele le ka mor'a ho hohlana, e bonts'a ho tiea ha ho lekana pakeng tsa batsamaisi le li-terminal. Ho na le mekhoa e 'meli e meholo ea lipalo indastering.
USCAR-21 (E sebediswa hangata masimong a dikoloi le a motlakase, sekgahla sa kgatello)
Karolelano ea Khatello (%) = 100×(1 - Sebaka sa karolo e tšelang ea mokhanni kamora ho korotla / Sebaka sa karolo e tšelang ea mokhanni ea khethiloeng pele ho horotla)
Mohlala: Mokhanni oa 50mm² pele a qaqametsa sebaka sa hae sa ho tšela se fokotsehile ka 20% kamora ho qaqametsa, ka karolelano ea khatello ea 20%.
VW 60330 (E sebelisoa haholo maemong a Jeremane le masimong a indasteri, tekanyo ea ho teteana)
Karolelano ea Khatello (%) = Sebaka sa ho tšela likarolo tsa mokhanni ka mor'a ho thiba / Sebaka sa ho tšela likarolo tsa mokhanni ka lebitso pele ho ho thiba × 100%
Mohlala: Haeba sebaka sa mokhanni oa kamora ho roba se etsa 80% ea sebaka sa pele, karolelano ea khatello ke 80%.
II. Tekanyo e ntle ea Khatello ea Khatello bakeng sa Crimping ea Terminal e Phahameng
Litlhoko tsa mantlha bakeng sa lits'ebetso tsa motlakase o phahameng (li-conductor tsa koporo, 6–400mm²): khanyetso e tlase ea ho kopana, matla a phahameng a ho hula, khanyetso e ntle ea mocheso le khanyetso ea ho thothomela. Mefuta e sebetsang e fapana ho latela thepa le boemo ba ts'ebetso.

III. Liphello tsa Karolelano e Phahameng ka ho Fetisisa kapa e Tlase ea Khatello
✅ Karolelano e tlase ea khatello (<15%)
Ho lekana ho sa thekeseleng pakeng tsa mokhanni le theminale, ho phahama ho hoholo ha khanyetso ea ho kopana. Ho hlahisoa ha mocheso o matla tlas'a motlakase o phahameng ka keketseho ea mocheso e fetang 50℃.
Matla a sa lekaneng a ho hula, a ka tlase ho 80% ea boleng bo tloaelehileng, a sekamela ho hlepha le ho oa ha a thothomela.
Likheo tse kholo li lumella mongobo le lerōle ho kena, ho potlakisa oxidation le mafome.
✅ Karolelano e phahameng haholo ea khatello (>30%)
Ho fetoha ho feteletseng kapa ho robeha ha lithapo tsa koporo, ho fokotsa bokgoni ba ho jara motlakase.
Ho petsoha le ho fetoha ha lebota la terminal ho lebisang tahlehelong ea matla a mechini.
Ho tsepamisa maikutlo kgatellong ya lehae ho baka ho petsoha tlasa katoloso ya nako e telele ya mocheso le ho kgutsufala.
IV. Lintlha tse Tharo tsa Bohlokoa tse Khethollang Karolelano e Loketseng ea Khatello

Motlakase: Khanyetso ea ho kopana ≤1.1 makhetlo a fetang a mokhanni oa bolelele bo lekanang, keketseho ea mocheso ≤30℃ kamora teko ea motlakase o phahameng oa hora e le 'ngoe
Mekaniki: Matla a ho hula a fihlela maemo a tloaelehileng (mokhanni ea likhoele ≥80N), ha ho na ho hlepha kapa likhoele tse robehileng
VI. Kakaretso: Lipalo tsa Bohlokoa bakeng sa Crimping ea motlakase o phahameng
Kontara ea koporo (6–400mm²): Karolelano e ntle ea khatello 18%–22%, karolelano ea ho hatelloa 78%–82%
Mokhanni oa aluminium: Karolelano ea khatello 30%–50%
Molao-motheo oa bohlokoa: Qoba ho se be le li-crimping tse lekaneng kapa tse feteletseng. Li-match dies, taolo e nepahetseng le tlhahlobo e tiileng ho felisa likotsi tsa khokahano e hlephileng.
Sehokelo sa motlakase se phahameng sa AMASS se sebedisa terminal e ka o thusang ho boloka dikgokelo tse tsitsitseng maemong a tshebediso a kang ho thothomela ha matla a hodimo, ditlamorao tse phetoang tsa mocheso o phahameng le o tlase, modumo o monyane, le motlakase o phahameng.
