Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission line technology, specifically to a conductor with a secondary conductor. Background Technology
[0002] Conductors refer to the materials used in wires and cables; in industry, they also refer to electrical wires. They are generally made of copper or aluminum, but some are made of silver wire (which has good electrical and thermal conductivity), and are used to conduct current or heat.
[0003] To monitor the power transmission status in real time, current power lines often incorporate secondary conductors for transmitting electrical signals. However, most existing power lines have poor anti-freezing properties, making them prone to freezing in low-temperature winter conditions, which can cause widespread power outages. Furthermore, power lines with secondary conductors typically require two connectors for equipment connection, which can easily lead to short circuits or leakage, posing certain safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide a conductor with a secondary conductor to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a conductor with a secondary conductor, comprising an insulation layer, an insulation layer disposed inside the insulation layer, a main conductor disposed inside the insulation layer, a secondary conductor disposed inside the insulation layer on one side of the main conductor, an insulation shell sleeved on the top of the insulation layer, a plurality of locking blocks disposed at the bottom end of the insulation shell, each of the locking blocks having a threaded groove on its outer surface, and a knob being threadedly connected to the outer surfaces of the locking blocks through the threaded grooves, and a connector disposed at the top end of the insulation shell.
[0006] Preferably, the outer surface of the main conductor is fitted with a first rubber sleeve, which wraps around the main conductor. Both the first and second rubber sleeves are made of rubber, which has excellent flexibility and good insulation effect, and can effectively reduce the probability of short circuits in the conductor.
[0007] Preferably, the outer surface of the secondary conductor is fitted with a second rubber sleeve, and the inner walls of both the first and second rubber sleeves are provided with a fireproof coating. The fireproof coating is composed of tert-propylene emulsion water-based material with various fire retardants and plasticizers added. When the conductor is accidentally exposed to fire during use, it can generate a uniform and dense sponge-like foam insulation layer, which can effectively inhibit and block the spread of flames.
[0008] Preferably, both the secondary conductor and the primary conductor extend beyond the top of the insulation layer, and the top of the secondary conductor is spirally wound around the top of the primary conductor, thus winding the primary conductor and the secondary conductor into one strand for easy connection.
[0009] Preferably, a limiting disc is provided on the outer surface of the insulating layer above several locking blocks to limit the knob and prevent the knob from leaving the outer surface of the locking block.
[0010] Preferably, a limit block is provided at the bottom edge of each of the locking blocks to prevent the knob from falling off the bottom of the locking block when it rotates towards the insulating layer.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This conductor with a secondary conductor, after being laid, involves winding the main conductor and the secondary conductor together at the connection end through an insulating shell and a connector. Then, the insulating shell is fitted, and the knob is turned towards the insulation layer to tighten several locking blocks and secure the insulation layer. Insulating tape is then wrapped around the connection point for reinforcement. The top ends of the main conductor and the secondary conductor 12 contact the bottom end of the connector, and the connector is connected to the equipment. This makes it easier to connect the conductor with the secondary conductor to the equipment without the need for two connectors, thus improving safety.
[0013] 2. This conductor with a secondary conductor, through the first rubber sleeve, the second rubber sleeve, and the insulation layer, effectively suppresses and blocks the spread of flames by means of fire-retardant coatings on the inner walls of the first and second rubber sleeves during use. The insulation layer also protects the primary and secondary conductors, reducing internal damage from low temperatures during winter use and preventing freezing. This makes the conductor with the secondary conductor more robust and suitable for a wider range of applications. Attached Figure Description

[0020] like Figures 1 to 3 As shown, the conductor with a secondary conductor in this embodiment includes an insulation layer 1. An insulation layer 9 is disposed inside the insulation layer 1. The insulation layer 9 is made of mineral fiber and possesses lightweight, heat-insulating, sound-absorbing, and corrosion-resistant properties, providing protection for the main conductor 11 and the secondary conductor 12. It reduces internal damage from low temperatures during winter use and prevents icing. The main conductor 11 is disposed inside the insulation layer 9, and the secondary conductor 12 is disposed inside the insulation layer 9 on one side of the main conductor 11. The secondary conductor 12 is used for signal transmission and monitoring of the main conductor 11, facilitating timely detection of whether the main conductor 11 has been cut. An insulating shell 6 is fitted onto the top of the insulation layer 1. Several locking blocks 3 are disposed at the bottom of the insulating shell 6. Each locking block 3 has a threaded groove 8 on its outer surface. A knob 4 is threadedly connected to the outer surfaces of the locking blocks 3 through the threaded grooves 8. A connector 7 is disposed at the top of the insulating shell 6, which integrates the main conductor 11 and the secondary conductor 12 into one strand, facilitating connection to other ports.
[0021] Specifically, a first rubber sleeve 10 is fitted onto the outer surface of the main conductor 11. The first rubber sleeve 10 wraps around the main conductor 11. Both the first rubber sleeve 10 and the second rubber sleeve 13 are made of rubber, which has excellent flexibility and good insulation effect, and can effectively reduce the probability of short circuits in the conductor.
[0022] Furthermore, a second rubber sleeve 13 is fitted onto the outer surface of the auxiliary conductor 12. The inner walls of both the first rubber sleeve 10 and the second rubber sleeve 13 are provided with a fireproof coating. The fireproof coating is composed of water-based tert-propylene emulsion material with various fire retardants and plasticizers added. When the conductor is accidentally exposed to fire during use, it can generate a uniform and dense sponge-like foam insulation layer, which can effectively suppress and block the spread of flames.
[0023] Furthermore, both the secondary conductor 12 and the primary conductor 11 extend beyond the top of the insulation layer 1, and the top of the secondary conductor 12 is spirally wound around the top of the primary conductor 11, thus winding the primary conductor 11 and the secondary conductor 12 into one strand for easy connection.
[0024] Furthermore, a limiting disc 5 is provided on the outer surface of the insulating layer 1 above several locking blocks 3 to limit the knob 4 so that the knob 4 will not leave the outer surface of the locking block 3.
[0025] Furthermore, limit blocks 2 are provided at the bottom edge of several locking blocks 3 to prevent the knob 4 from falling off the bottom of the locking block 3 when it rotates towards the insulating layer 1.
[0026] The usage method of this embodiment is as follows: After the wires are laid, the main wire 11 and the secondary wire 12 are wound together at the connection end, and then the insulating shell 6 is fitted on. Then, the knob 4 is turned to move towards the insulating layer 1, and several locking blocks 3 are contracted to clamp the insulating layer 1. Then, insulating tape is wrapped around the connection position for reinforcement. The top ends of the main wire 11 and the secondary wire 12 are in contact with the bottom end of the connector 7. The connector 7 is connected to the equipment. During use, the main wire 11 and the secondary wire 12 are provided with fireproof coatings on the inner walls of the first rubber sleeve 10 and the second rubber sleeve 13, which effectively suppresses and blocks the spread of flames. The insulation layer 9 provides protection for the main wire 11 and the secondary wire 12, reducing the damage to the interior caused by low temperature during winter use and making it less prone to freezing.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
