GT-50 copper connector

(1 đánh giá)

Đầu nối đồng GT-50

GT-50 copper connector is a through-type straight connecting tube designed to join two copper cable ends with a suitable nominal cross-sectional area of 50mm² by crimping. The model shown in the dimensional table is GT-1-50, with an outer diameter D of 13mm, an inner diameter d of 10mm and a length L of 70mm.

  • Model: GT-50
  • Suitable cable cross-sectional area: 50mm²
  • Outer diameter D: 13mm
  • Inner diameter d: 10mm
  • Length L: 70mm

GT-50 copper connector is a straight connecting tube used to join two copper conductor ends with a suitable nominal cross-sectional area of 50mm². Its through-type design allows the conductors to be inserted from both ends before crimping.

This product is a straight cable joint without a palm or bolt hole, unlike an SC copper cable lug. The GT-50 is therefore intended for joining two copper cable sections along the same cable route rather than terminating a cable onto a busbar, circuit breaker or electrical terminal.

Construction features of the GT-50 connecting tube

  • Cylindrical tube design with conductor entry from both ends.
  • Through-type construction suitable for straight joining of two copper cables.
  • Dimensions are identified by outer diameter D, inner diameter d and overall length L.
  • No bolt hole or cable lug palm, so it is not a replacement for a bolted copper cable lug.
  • Stable electrical and mechanical performance depends on selecting the correct connector, conductor size, crimping tool and die, and following the proper installation method.

Applications of the 50mm² copper cable connector

The GT-50 is used to join two copper conductor sections with a suitable nominal cross-sectional area of 50mm². Typical applications may include:

  • Joining two copper cable sections along the same electrical route.
  • Extending a copper cable inside an electrical cabinet or power distribution system.
  • Repairing a cable section where an approved crimped joint is permitted by the technical design.
  • Installing a straight cable joint where a bolted cable lug is not required.

For cable termination onto a busbar or electrical device, refer to the SC copper cable lug category. For insulated straight connectors, refer to the GTY straight connector category.

How to select the correct GT-50 copper connector

Check the nominal cable cross-sectional area

The GT-50 is specified for a suitable cable cross-sectional area of 50mm². Do not select the connector based only on the outside diameter of the cable insulation. A nominal conductor size of 50mm² is also not the same as an actual conductor diameter of 50mm.

Check the actual conductor dimensions

The connecting tube has an inner diameter of 10mm. Before installation, check that the stripped copper conductor can be inserted correctly without excessive force or abnormal clearance.

Distinguish GT from GTY connectors

The GT-50 shown in the supplied document is a through-type copper connecting tube. It should be distinguished from the GTY straight connector for 50mm² cable, as the two connector types do not have identical construction or application requirements.

Select the correct crimping tool and die

Use a crimping tool and die that are compatible with the connector type, cable size and applicable installation instructions. Do not determine the crimping force, number of crimps or crimping positions without suitable technical documentation.

Basic installation procedure

  1. Disconnect and isolate the power supply, then verify that the work area is electrically safe.
  2. Confirm the GT-1-50 model and a suitable 50mm² copper conductor.
  3. Clean the conductor surfaces and remove dirt, oil or other contaminants from the contact area.
  4. Insert the two conductor ends into the tube from opposite sides and align them according to the installation requirements.
  5. Crimp the connector using a compatible crimping tool and die.
  6. Inspect the mechanical security, connector deformation and conductor position after crimping.
  7. Apply suitable insulation and mechanical protection to the completed joint according to the cable system design.

The stripping length, crimping force and number of crimping points must be determined according to the conductor construction, connector, tool, die and applicable installation instructions. A single fixed value should not be applied to every installation.

Technical and safety notes

  • Use the connector for copper conductors only. Do not use this copper connecting tube to directly join an aluminium conductor.
  • Do not use the GT-50 as a substitute for a cable lug with a bolt hole.
  • Do not crimp the connector with an incorrect die size or an incompatible tool.
  • Do not insert heavily oxidised, contaminated or damaged conductors into the connector.
  • Apply suitable insulation and protection after completing the crimped joint.
  • Installation should be carried out by qualified personnel after the electrical system has been safely isolated.

Frequently asked questions about the GT-50

What cable size is the GT-50 used for?

According to the supplied dimensional table, the GT-1-50 is intended for a suitable cable cross-sectional area of 50mm².

What are the dimensions of the GT-50 connector?

The connector has an outer diameter D of 13mm, an inner diameter d of 10mm and an overall length L of 70mm.

Is the GT-50 a bolted cable lug?

No. The GT-50 is a through-type straight connecting tube used to join two conductor ends. It does not have a cable lug palm or bolt hole.

Can the GT-50 join a copper cable to an aluminium cable?

This copper connecting tube should not be used to directly join copper and aluminium conductors. A suitable transition connector must be selected for connections between different conductor metals.

Can any 50mm² die be used with every crimping tool?

No. Compatibility must be checked between the crimping tool, die, connector type and conductor construction before installation.

Order the GT-50 copper connector for 50mm² cable

To select the correct GT-50 copper connector, provide the cable cross-sectional area, conductor type, straight-joint requirement and information about the crimping tool being used. Truong Phat can assist with checking the GT-1-50 model against the documented dimensions of D 13mm, d 10mm and L 70mm.

You may also refer to the straight connector for 35mm² cable and the straight connector for 70mm² cable when comparing adjacent cable sizes.
