GT-185 copper connecting tube

(1 đánh giá)

đầu nối đồng GT-185

GT-185 copper connecting tube is a straight-through sleeve designed to join two 185mm² copper cable conductors by crimping. According to the catalog, the product has a 24 mm outer diameter, 19 mm inner diameter and 100 mm overall length.

Before installation, verify the cable cross-sectional area and actual conductor diameter against the tube bore, then select a compatible crimping tool and die. Do not use this copper tube to connect aluminum conductors directly. Contact Trường Phát with the required model, quantity and cable details for specification checking and quotation support.

Where two cable sections must be joined in line without using a bolted terminal lug, the GT-185 copper connecting tube provides a straight-through crimp connection. The sleeve accepts conductors from both ends and is installed using a suitable mechanical or hydraulic crimping tool. According to the supplied catalog, model GT-185 has a 24 mm outer diameter, 19 mm inner diameter and 100 mm overall length.

This product is a straight cable joint sleeve, not a bolted cable lug. It is therefore intended for joining copper cable to copper cable rather than terminating a conductor directly onto a busbar, MCCB terminal or equipment stud.

What is the GT-185 copper connecting tube used for?

The primary function of GT-185 is to create an in-line joint between two compatible copper cable conductors. Each stripped conductor is inserted from one end of the tube, after which the sleeve is compressed with a suitable crimping tool and die.

The product may be considered for cable extension work, replacement of a damaged cable section or connection of two matching copper conductors. Actual suitability also depends on conductor material, strand construction, conductor diameter after insulation removal and the technical requirements of the electrical system.

  • Joining two compatible copper cable conductors in a straight line.
  • Extending a copper cable route during installation or repair work.
  • Creating an in-line crimped joint along the cable axis.
  • Connecting cables where no bolted palm or mounting hole is required.

GT-185 must not be treated as an SC or DT cable lug for direct connection to equipment. Where a bolted connection is required, select a cable lug with the correct palm shape and stud-hole diameter.

GT-185 dimensions and specifications

Specification Symbol Value
Model Cat.No. GT-185
Suitable nominal cable cross-section - 185mm²
Outer diameter D 24 mm
Inner diameter d 19 mm
Overall length L 100 mm
Connection type - Straight-through connecting tube
Installation method - Crimping with a suitable tool

The D, d and L values are taken directly from the GT-185 row in the supplied catalog. The 19 mm inner diameter is the tube bore, not the actual conductor diameter of every 185mm² cable. Cables with the same nominal cross-sectional area may have different strand constructions and finished conductor diameters, so the cable datasheet or actual conductor size should be checked before ordering.

Straight-through construction and suitable applications

The GT series is identified by its straight cylindrical body, two open ends and absence of a bolted palm. This construction allows conductors to be inserted from opposite directions while keeping the finished joint aligned with the cable route.

With an overall length of 100 mm, GT-185 provides space for inserting both conductors and forming the crimped connection. However, the supplied catalog does not specify stripping length, crimping force, number of crimps or crimping positions. These values must not be assumed and should instead follow the approved installation procedure, cable construction, die system and crimping equipment instructions.

Situations where GT-185 may be suitable

  • Both conductors are copper cables.
  • The required nominal cable cross-section is 185mm².
  • The installation requires a straight sleeve rather than a bolted terminal lug.
  • A compatible crimping tool and die are available.
  • The installation includes suitable insulation and mechanical protection after crimping.

Do not use the GT-185 copper tube to connect an aluminum conductor directly. For aluminum cable or copper-to-aluminum transition joints, use a connector specifically designed for the relevant conductor materials.

How to verify the correct connector before ordering

Model selection should not be based only on the 185mm² marking. The cable specification, tube bore and installation conditions must also be checked.

  1. Confirm the conductor material: GT-185 is a copper connecting tube and is intended for a compatible copper cable connection. It must not be used directly with aluminum conductors.
  2. Check the nominal cross-sectional area: verify the 185mm² rating from the cable marking or technical documentation.
  3. Compare the conductor diameter: the catalog lists a 19 mm tube bore. Confirm that the stripped conductor fits correctly without excessive looseness or forced insertion.
  4. Check installation space: the connector is 100 mm long and 24 mm in outer diameter. Additional working space is required for the crimping tool and final insulation system.
  5. Check the crimping equipment: the die must be compatible with the sleeve type, tube dimensions and cable conductor. Do not select a die only by visual appearance.

For cable terminations that require a bolted palm, refer to the SC copper cable lug range or the DT copper cable lug range. These products are used for equipment termination and must not be confused with the GT-185 straight connecting tube.

Preparation, crimping and safety checks

Cable jointing must only be performed after the circuit has been isolated and verified as de-energized. Installers should use appropriate protective equipment, approved tools and the electrical safety procedure applicable to the project.

  1. Disconnect and isolate the power supply, then verify the absence of voltage.
  2. Confirm the GT-185 model and inspect the tube for deformation, contamination or physical damage.
  3. Prepare both cable ends and remove any damaged conductor section.
  4. Strip the insulation according to the approved installation procedure.
  5. Insert the copper conductors from opposite ends and verify their positions before crimping.
  6. Use a compatible crimping tool and die to form the connection.
  7. Inspect the mechanical stability, crimped surface and conductor condition.
  8. Apply an insulation and protection system suitable for the voltage level, environment and project requirements.

Do not independently specify the crimping force, number of crimps, crimping positions or stripping length without applicable technical instructions. Do not grind down the conductor to make it fit and do not add loose conductor strands to compensate for an incorrectly sized connector.

Frequently asked questions about GT-185

Is GT-185 a bolted cable lug?

No. GT-185 is a straight-through connecting tube with two open ends and no mounting hole. It joins two cable conductors, whereas SC or DT cable lugs terminate a conductor onto a busbar, MCCB or equipment stud.

Is the 19 mm inner diameter the actual diameter of every 185mm² conductor?

No. The 19 mm value is the internal diameter of the tube. The actual conductor diameter depends on the strand construction and cable design.

Can GT-185 be used with aluminum cable?

Do not use this copper tube to connect aluminum conductors directly. Select a connector designed for aluminum cable or for a copper-to-aluminum transition.

Can GT-150 or GT-240 replace GT-185?

They should not be substituted solely because their appearance is similar. GT-150 and GT-240 have different bore diameters, outer diameters and lengths, which may make them incompatible with a 185mm² cable.

How many crimping points are required for GT-185?

The supplied catalog does not state the number of crimps. This must be determined from the cable type, crimping tool, die system and approved installation procedure.

What information should be provided when requesting a quotation?

Provide the GT-185 model, required quantity, conductor material, nominal cable cross-section, actual conductor diameter where available and the crimping tool or die system being used.

Request a quotation for GT-185 copper connecting tube

To request a quotation for the GT-185 copper connecting tube, send the required quantity, copper cable specification, dimensions to be checked and delivery location. Trường Phát can help verify the catalog dimensions of D 24 mm, d 19 mm and L 100 mm, while also confirming that a straight connecting tube is required instead of a bolted cable lug.

Customers may also view the copper and aluminum cable lug category or submit an inquiry through the Trường Phát contact page.
