电缆接头（防水接头）是电缆分支箱中不可缺少的部分，由于电缆接头附件种类、形式、规格较多;质量参差不齐;施工人员技术水平高低不等;电缆接头运行方式和条件各异，致使交联电缆。
Cable
joints (waterproof joints) are an indispensable part of cable branch
boxes, as there are many types, forms, and specifications of cable joint
accessories; Uneven quality; The technical level of construction
personnel varies; The operation mode and conditions of cable joints
vary, resulting in cross-linked cables.
接头发生故障的原因各不相同。
The reasons for connector failure vary.
交联电缆是交联聚乙烯绝缘电缆的型线 流水槽模具 景观石 检查井钢模具 保定通风管道 隔离墩模具 保定保洁公司简称。交联电缆适用于工频交流电压500KV及以下的输配电线路中。目前高压电缆绝大部分都采用了交联聚乙烯绝缘。
Crosslinked
cable is the abbreviation for cross-linked polyethylene insulated
cable. Crosslinked cables are suitable for transmission and distribution
lines with power frequency AC voltage of 500KV and below. Currently,
the vast majority of high-voltage cables are insulated with cross-linked
polyethylene.
由于交联电缆与油纸电缆的介质不同，接头发生故障的原因有很大的差异，油纸电缆接头发生故障主要是绝缘影响，而交联电缆接头发生故障主要是导体连接。交联电缆允许运行温度高，对电缆接头就提出了更高的要求，使接头发热问题就显得更为突出。接触电阻过大、温升加快、发热大于散热促使接头的氧化膜加厚，又使接触电阻更大，温升更快。如此恶性循环，使接头的绝缘层破坏，形成相间短路，引起爆炸烧毁。
Due
to the different media between cross-linked cables and oil-paper
cables, there are significant differences in the causes of joint
failures. The main reason for joint failures in oil-paper cables is
insulation, while the main reason for joint failures in cross-linked
cables is conductor connections. Crosslinked cables allow for high
operating temperatures, which puts higher demands on cable joints,
making the problem of joint heating even more prominent. Excessive
contact resistance, accelerated temperature rise, and heating greater
than heat dissipation cause the oxide film on the joint to thicken,
which in turn increases the contact resistance and accelerates the
temperature rise. This vicious cycle causes the insulation layer of the
joint to be damaged, forming a phase to phase short circuit and causing
explosion and burning
