拉断力大于2.766kg.重量0.144kg/米。
延长系数0.79 m,电线铠甲(外层/英寸)18/12HS 工作电压1200V直流电
绝缘是0.67mm的FEP或ETFE
还要如下要求(HS镀锌钢铠装)
HSgalvanized steel armor wires 12 of internal diameter 0.79 mm each (0.031") and external threads 18 of 0.79 mm (0.031").
This type of cable must be matched to records in geothermal wells run of 3 000m depth using electronic tools such as calipers, CBL, detonation of explosivesand CCL.
