[0023] The bonding component 20 includes a copper layer 21 disposed at the inner center of the tin-zinc alloy layer 10, two steel wire bundles 22 are disposed inside the copper layer 21, the two steel wire bundles 22 are disposed in parallel and spaced apart, a first plastic fiber 23 and a plurality of steel fibers 24 disposed around the first plastic fiber 23 are disposed at the inner center of the steel wire bundle 22, and a second plastic fiber 25 is disposed between the two steel fibers 24 on the same side and surrounds the first plastic fiber 23 sideways;
[0024] The bonding component 20 is provided with two steel wire bundles 22, which can correspondingly increase the carrying capacity of the copper-clad steel grounding wire. Since the two steel wire bundles 22 are arranged side by side and spaced apart, the current carrying capacity of the corresponding copper layer 21 is larger than that of a single steel wire bundle 22. Each steel wire bundle 22 includes steel fibers 24, first plastic fibers 23 and second plastic fibers 25, so that the copper-clad steel grounding wire has greater overall strength and better flexibility, so that the copper-clad steel wire can be bent well.
[0025] The pressure-resistant component 30 includes a pressure-resistant layer 31 disposed inside the tin-zinc alloy layer 10 and outside the copper layer 21, a plurality of first pressure-resistant parts 32 are disposed on the surface of the copper layer 21 and inside the pressure-resistant layer 31, and second pressure-resistant parts 33 are disposed inside the first pressure-resistant parts 32;
[0026] By providing a pressure-resistant layer 31 and utilizing the elasticity of silicone, the pressure on the copper layer 21 is buffered; by providing the first pressure-resistant component 32 and the second pressure-resistant component 33, the pressure resistance of the grounding wire is further enhanced to offset most of the pressure, thereby ensuring the normal operation of the grounding wire and increasing its service life; and by providing an insulating layer 50 to wrap the adhesive component 20 and the pressure-resistant component 30, the safety of the staff is protected.
[0027] A plurality of indicator grooves 40 are arranged on the surface of the tin-zinc alloy layer 10 along its length direction, and the distance between two consecutive indicator grooves 40 is 1M;
[0028] The copper-clad steel grounding wire is provided with indicator grooves 40 at equal intervals. Through the setting of the indicator grooves 40, the length of the device can be displayed, so that the operator can select the copper-clad steel grounding wire of the specified length.
[0029] The steel wire harness 22 is made of polyethylene, and the first plastic fiber 23, the steel fiber 24 and the second plastic fiber 25 are twisted together in a spiral shape.
[0030] The plurality of first pressure-resistant parts 32 are distributed in an annular shape with equal distances about the axis of the copper layer 21 , and the pressure-resistant layer 31 is made of silicone.
[0031] An insulating layer 50 is sleeved on the outer side of the pressure-resistant layer 31 , and the insulating layer 50 is made of rubber.
[0032] The tin-zinc alloy layer 10 is a Sn-Zn-In-Ag alloy and has a thickness of 1 to 3 mm;
[0033] The Sn-Zn-In-Ag alloy does not contain lead, and its melting point is close to the eutectic point of the traditional Sn-Pb solder, 183°C. The tin-zinc alloy layer 10 has low toxicity and low cost, and ensures the conductivity and corrosion resistance of the copper-clad steel grounding wire.
[0034] The working principle of the high-insulation copper-clad steel grounding wire provided by the utility model is as follows:
[0035] Step 1: two steel wire bundles 22 are arranged in the bonding assembly 20, which can increase the carrying capacity of the copper-clad steel grounding wire accordingly. Since the two steel wire bundles 22 are arranged side by side and spaced apart, the current carrying capacity of the corresponding copper layer 21 is larger than that of a single steel wire bundle 22. Each steel wire bundle 22 includes a steel fiber 24, a first plastic fiber 23 and a second plastic fiber 25, so that the copper-clad steel grounding wire has a greater overall strength and better flexibility, so that the copper-clad steel wire can be bent well.
[0036] Step 2: By setting up a pressure-resistant layer 31 and utilizing the elasticity of silicone to buffer the pressure on the copper layer 21, by setting up the first pressure-resistant component 32 and the second pressure-resistant component 33, the pressure resistance of the grounding wire is further enhanced to offset most of the pressure, thereby ensuring the normal operation of the grounding wire and increasing its service life. By setting up an insulating layer 50 to wrap the adhesive component 20 and the pressure-resistant component 30, the safety of the staff is protected.
[0037] Compared with the related art, the high-insulation copper-clad steel grounding wire provided by the utility model has the following advantages:
[0038] Beneficial effects:
[0039] By cooperating with each other in the various parts of the device, the device can provide a pressure-resistant layer 31 and utilize the elasticity of silicone to buffer the pressure on the copper layer 21. By providing the first pressure-resistant component 32 and the second pressure-resistant component 33, the pressure resistance of the grounding wire is further enhanced to offset most of the pressure, ensure the normal operation of the grounding wire, and increase its service life.
