Embodiment 1
[0022] In this embodiment, the core is a zinc oxide core of a high-energy resistor, such as figure 1 As shown, it includes a high-temperature cable 1, a silicone rubber jacket 2, a core 3, and a lower electrode 4. The high-temperature cable 1 is arranged at the top end of the core 3, the lower electrode 4 is arranged at the bottom end of the core 3, and the silicone rubber The jacket 2 is wrapped around the core 3 and the high-temperature cable 1. The high-temperature cable 1 serves as the upper electrode of the core 3, and the lower electrode 4 is fixed on the switch cabinet by bolts.
[0023] (1) Put the core 3 into an oven at 100°C for 2 hours;
[0024] (2) Weld the high temperature cable 1 on the top of the preheated core 3, and then put the core 3 into the mold containing the silicone rubber melt, so that the silicone rubber connects the core 3 and the core 3 to the high temperature The connection of cable 1 is completely covered and molded according to the process: such as f...
Embodiment 2
[0033] The product made in this embodiment is a 24KV lightning rod, and this embodiment includes the following steps:
