技术领域 technical field
本实用新型涉及一种电缆，更具体的讲是一种耐寒矿用高压橡套软电缆。 The utility model relates to a cable, in particular to a cold-resistant high-voltage rubber-sheathed soft cable for mining.
背景技术 Background technique
矿用电缆是指煤矿开采工业上用的地面设备和井下设备用电线电缆产品，其中包括采煤机、运输机上的通信、照明与信号设备用电缆，以及电钻电缆、帽灯电线和移动变电站用的电源电缆等。随着社会不断向前发展，用户对电缆性能要求也越来越高，对野外用高压电力电缆要求也一样，要求也是越来越高，因为野外的环境较为恶劣，比如北方的冬季温度一般在零下四五十度，还有就是野外移动用高压软电缆要求有良好的移动特性，经常频繁的碰撞以及拉扯，所以该电缆必须具有耐寒、耐撕磨、抗拉等特性。传统的矿用电缆电压低、抗拉强度低、使用寿命短、也不能满足耐寒环境的要求。 Mining cables refer to wire and cable products for ground equipment and underground equipment used in the coal mining industry, including cables for communication, lighting and signal equipment on coal shearers and conveyors, as well as cables for electric drills, cap lamp wires and mobile substations. power cables etc. With the continuous development of society, users have higher and higher requirements for cable performance, and the requirements for high-voltage power cables used in the field are also higher and higher, because the environment in the field is relatively harsh, such as the winter temperature in the north. Forty to fifty degrees below zero, and the high-voltage flexible cable for field movement requires good movement characteristics, frequent collisions and pulls, so the cable must have characteristics such as cold resistance, tear resistance, and tensile resistance. Traditional mining cables have low voltage, low tensile strength, short service life, and cannot meet the requirements of cold-resistant environments.
发明内容 Contents of the invention
针对以上不足，本实用新型提供了一种耐寒矿用高压橡套软电缆。 Aiming at the above deficiencies, the utility model provides a cold-resistant mine high-voltage rubber-sheathed flexible cable.
一种耐寒矿用高压橡套软电缆，包括设置在外护套内的主线芯、辅助线芯和加强线芯，电缆由内到外依次为加强线芯、主线芯、内护套、半导电阻水层Ⅰ、辅助线芯、半导电阻水层Ⅱ和外护套，所述主线芯有内到外依次由导体、半导电胶布带、共挤层和镀锡铜丝编织层。 A cold-resistant high-voltage rubber-sheathed flexible cable for mines, including a main core, an auxiliary core and a reinforced core arranged in an outer sheath. Water layer I, auxiliary wire core, semi-conductive resistance water layer II and outer sheath, the main wire core has a conductor, a semi-conductive tape, a co-extruded layer and a tinned copper wire braided layer from inside to outside.
上述镀锡铜丝编织兼做地线。 The above-mentioned tinned copper wire braid also serves as the ground wire.
上述辅助线芯由镀锡铜丝绞合而成，辅助线芯有时作监视线芯用，其作用是与电缆的接地线芯一起构成监视回路，以实现对接地系统完整性的连续监视，当发生系统短路故障时同时起到泄流的作用。在辅助线芯内、外层分别绕包半导电阻水层Ⅰ、半导电阻水层Ⅱ，以提高电缆径向阻水效果。 The above-mentioned auxiliary wire core is twisted by tinned copper wire, and the auxiliary wire core is sometimes used as a monitoring wire core. In the event of a system short-circuit fault, it also acts as a drain. The inner and outer layers of the auxiliary core are respectively wrapped with semi-conductive resistance water layer I and semi-conductive resistance water layer II to improve the radial water resistance effect of the cable.
上述加强线芯是芳纶加强线芯。 The above-mentioned reinforced wire core is an aramid fiber reinforced wire core.
上述共挤层为导体屏蔽层、绝缘层、绝缘屏蔽层。 The above-mentioned co-extrusion layer is a conductor shielding layer, an insulating layer, and an insulating shielding layer.
上述绝缘层为乙丙胶绝缘层，目前，国内橡套电缆额定电压等级最高为8.7/10 kV，而高压金属屏蔽橡套软电缆的额定电压则为8.7 /15 kV，这就对电缆的绝缘层提出了更高的要求，即要求橡胶绝缘料中杂质含量尽量少，选用了乙丙橡胶绝缘用于高电压等级的电缆绝缘，乙丙橡胶的电气性能和耐高低温性能均较好，能满足高压电缆的使用要求以保证成品电缆经受交流50 Hz、40KV 电压试验5 min 电缆不击穿。 The above insulation layer is ethylene propylene rubber insulation layer. At present, the rated voltage level of domestic rubber-sheathed cables is up to 8.7/10 kV, while the rated voltage of high-voltage metal-shielded rubber-sheathed flexible cables is 8.7 /15 kV, which affects the insulation of cables. The layer puts forward higher requirements, that is, the impurity content in the rubber insulating material is required to be as small as possible. Ethylene-propylene rubber insulation is used for high-voltage cable insulation. Ethylene-propylene rubber has good electrical properties and high and low temperature resistance. Meet the requirements for the use of high-voltage cables to ensure that the finished cables withstand AC 50 Hz, 40KV voltage test for 5 minutes without breakdown.
上述绝缘屏蔽层是由乙烯-醋酸乙烯共聚物和炭黑组成的半导电层。 The above insulating shielding layer is a semiconductive layer composed of ethylene-vinyl acetate copolymer and carbon black.
上述外护套采用氯化聚乙烯橡皮。 The above outer sheath is made of chlorinated polyethylene rubber.
上述外护套内添加有耐寒材料。 Cold-resistant materials are added in the outer sheath.
