Description

Dowells Brass Cable Gland 45mm (1-3/4”) – Single/Double Compression

The Dowells Brass Cable Gland 45mm (1-3/4”) is an industrial cable-entry solution available in Single Compression and Double Compression configurations. Thunderbolt Electromech currently lists the Dowells 45mm size alongside other Dowells cable-gland sizes, making it part of the company’s broader industrial Cable Gland range.

The 45mm designation is also expressed as 1-3/4 inch, which is useful when project specifications, purchase orders or cable-entry requirements use imperial terminology.

However, 45mm should not automatically be interpreted as a 45mm cable outside diameter. Cable-gland selection depends on the actual cable OD, construction, armour, gland configuration and required thread. This distinction is also reflected in cable-gland discussions where users regularly encounter confusion between gland/thread designations and the actual cable size.

Dowells 45mm Single Compression Cable Gland

The Dowells 45mm Single Compression Cable Gland is intended for compatible cable-entry applications where a single-compression configuration is specified.

For procurement, engineers should verify the actual cable dimensions and required thread rather than ordering solely because the cable is described as a particular conductor size.

Single Compression Specifications

Brand	Dowells
Product Type	Brass Cable Gland
Compression Type	Single Compression
Nominal Size	45mm
Imperial Size	1-3/4”
Material	Brass
Application	Cable entry / termination
Selection	Cable OD, construction, thread & application

Important

A 45mm Cable Gland is not necessarily intended for a 45mm cable OD. The actual cable OD and manufacturer’s applicable selection range should be checked before ordering.

This is one of the most common cable-gland purchasing mistakes. Our article What Size Cable Gland Do I Need for My Project? explains why actual cable OD is more useful than selecting a gland based only on conductor cross-section.

Dowells 45mm Double Compression Cable Gland

The Dowells 45mm Double Compression Cable Gland is intended for applications where a double-compression configuration is required, particularly where cable construction and armour requirements call for an appropriate armoured-cable gland arrangement.

Double-compression cable glands are commonly associated with armoured cable termination because the gland arrangement can provide retention/sealing around the cable and appropriate armour treatment.

Before purchasing, verify:

• Cable overall diameter
• Armour type
• Cable construction
• Required gland configuration
• Thread requirement
• Installation environment
• Project specification

Which one should you choose?

Choose Single Compression when the cable and project specification call for a single-compression gland.

Choose Double Compression when the cable construction and project specification require a double-compression arrangement, particularly for applicable armoured cables.

Do not select between the two merely because both are labelled 45mm.

How to Select the Correct Dowells 45mm Cable Gland

Before placing an order, check these parameters:

1. Measure the cable OD

Measure the finished outside diameter of the cable or obtain it from the cable manufacturer’s datasheet.

2. Check cable construction

Determine whether the cable is:

• Armoured
• Unarmoured
• Single-core
• Multicore
• Power cable
• Control cable
• Other project-specific construction

3. Select Single or Double Compression

The cable construction and project specification determine the appropriate gland configuration.

4. Confirm the thread

Do not assume that the nominal 45mm designation automatically tells you every thread dimension required for the installation.

5. Check the installation environment

Consider whether the gland will be installed indoors, outdoors or in another specified environment and select the appropriate product specification.

6. Confirm the manufacturer’s selection data

For critical industrial orders, match the actual cable dimensions against the manufacturer’s applicable gland selection data before dispatch.

Frequently Asked Questions

1. What is a Dowells Brass Cable Gland 45mm (1-3/4”)?

It is a Dowells brass Cable Gland identified in the 45mm / 1-3/4″ size category and available through Thunderbolt in Single Compression and Double Compression configurations. Thunderbolt currently lists this product as a selectable multi-variant product.

2. Does 45mm Cable Gland mean the cable OD must be 45mm?

No. The 45mm designation should not automatically be treated as the acceptable cable outside diameter. The actual cable OD, gland selection data, cable construction and thread must be checked.

This distinction is important because cable-gland sizing conventions can cause confusion between nominal dimensions, entry/thread dimensions and the cable’s usable diameter.

3. What is the difference between Dowells 45mm Single and Double Compression Cable Glands?

The two configurations have different cable-entry/termination arrangements. The appropriate choice depends on cable construction and the project requirement. Double Compression is generally the configuration to investigate for applicable armoured-cable installations, while Single Compression is selected where the project calls for that configuration.

4. Can I use the Dowells 45mm Single Compression Gland for an armoured cable?

Do not assume that it is suitable simply because the size is 45mm. Check the specific Dowells product configuration and the cable construction. If the installation requires armour clamping/termination, select the applicable armoured double-compression configuration.

5. How do I choose the correct 45mm Cable Gland?

Start with the actual cable outside diameter, then check cable construction, armouring, gland type, thread and installation requirements. Do not choose the gland based only on cable conductor size in sq.mm.

6. Is 1-3/4 inch the same as 45mm?

1-3/4 inch is the imperial designation used for the 45mm product size. However, this does not mean that a cable measuring exactly 45mm OD is automatically compatible.

7. Can I use the same 45mm gland for different cable sizes?

Only if the specific manufacturer’s applicable cable-selection range covers the actual cable OD. The nominal 45mm designation alone is not enough to determine compatibility.

8. Does cable sq.mm determine the Cable Gland size?

No. Conductor cross-section and finished cable outside diameter are different measurements. Two cables with similar conductor sizes can have different overall diameters depending on construction, insulation, armour and sheath.

9. What thread should I use with a Dowells 45mm Cable Gland?

The required thread must be confirmed from the specific gland configuration and the enclosure/equipment entry. Do not assume the 45mm product designation alone identifies every thread parameter.

10. Is a brass Cable Gland suitable for industrial applications?

Brass cable glands are widely used in electrical and industrial cable-entry applications, but suitability depends on the particular product specification and installation environment. Select the product according to the cable, enclosure, thread and environmental requirements.

11. Where can I buy Dowells Brass Cable Gland 45mm in India?

Thunderbolt Electromech India Pvt. Ltd. currently lists the Dowells Single/Double Compression Brass Cable Gland 45mm (1-3/4″) in its product range.

12. Should I choose Single or Double Compression for my project?

Use the project specification and cable construction as the deciding factors. For an armoured cable requiring appropriate armour termination, investigate the applicable Double Compression configuration. For other compatible applications specified for single compression, choose Single Compression.
