Intambo eguquguqukayo evikelayo ekushiseni nasezicishamlilweni enombheki wethusi ohlanganiswe nge-PVC, umgogodla ongu-1 × 70 mm², amandla kagesi abekiwe 450/750 V. Izinga: Yakhiwe ngokuhambisana ne-GB/T 5023 / JB/T 8734 (izintambo ezine-PVC ezibekiwe 450/750 V kanye nezintambo eguquguqukayo); ukusebenza kokuvikela ekushiseni nasezicishamlilweni ngokwe-GB/T 19666 kanye ne-GB/T 19216 (IEC 60331). Izinhlelo zokusetshenziswa: Izintambo ezingaguquki ezibalulekile emlilweni — ukukhanyisa okuphuthumayo, izinhlelo zomsindo womlilo kanye nokuphuma ezakhiweni; izixhumi eguquguqukayo ngaphakathi kwama-switchgear namaphaneli okusabalalisa. Izici: Umbheki wethusi oguquguqukayo wokugoba kalula ezindaweni ezincane; ukuvikela ekushiseni nasezicishamlilweni, ukugcina ubuqotho besekethe phansi komlilo; ukuhlanganisa nge-PVC. Amapharamitha obuchwepheshe: umgogodla ongu-1 × 70 mm² wombheki wethusi oguquguqukayo, amandla kagesi abekiwe 450/750 V, i-AC.
