Line Fittings | XGU-1 ~ XGU-4 Fixed Type Suspension Clamp for Overhead Line Conductors

Line Fittings | XGU-1 ~ XGU-4 Fixed Type Suspension Clamp is an overhead line fitting used to support bare conductors at the suspension towers and poles of power distribution and transmission lines. It is a fixed (rigid-trough) type suspension clamp in which the conductor is held in a curved boat-shaped trough by a keeper plate and U-bolts, and the clamp body swings freely on a top pivot pin so that it can follow the conductor under wind and ice loads. The XGU series is the standard suspension clamp of overhead distribution and transmission lines. The clamp body and keeper are made of hot-dip galvanized malleable iron or cast steel; the trough is curved with flared bell-mouth ends to limit bending stress and protect the conductor strands. The series is graded XGU-1 to XGU-4 by conductor diameter range and rated failure load, so one clamp family covers conductors from small distribution sizes up to large transmission conductors. The hanger ears accept a standard ball-eye, socket-clevis or U-clevis for connection to the insulator string. YAOGU supplies it together with cable clamps, cable lugs, terminal blocks and the complete range of high and low voltage switchgear as a one-stop power equipment solution.

Model:
XGU-1~4

Parameter	Line Fittings
Common Models	XGU-1~4
Construction	Hot-dip galvanized malleable iron or cast steel clamp body with curved trough and flared bell-mouth ends; separate keeper plate held by two U-bolts with hex nuts, flat washers and lock washers. Twin hanger ears with top pivot pin and cotter pin (or split pin) allowing the clamp to swing in the line direction; hanger connects to the insulator string through ball-eye, socket-clevis or U-clevis fittings.
Core Function & Performance	Supports the bare conductor at the suspension tower or pole and transfers its vertical and transverse loads to the insulator string, while allowing the conductor to swing and limiting the bending stress at the clamp mouth; grip strength and slip load are matched to the conductor so that the clamp holds under unbalanced tension without damaging the strands.
Technical Specs & Ratings	• Applicable line voltage: 10 kV to 500 kV overhead lines (by clamp type) • Standards: GB/T 2314, IEC 61284 • Main components: Clamp body (trough), keeper plate, U-bolts, hex nuts, washers, hanger ears, pivot pin, cotter pin • Applicable conductor diameter range, rated failure load, slip load and dimensions for each grade: configured according to the conductor specification, please contact us.
Typical Application Scenarios	Suspension points of overhead power distribution and transmission lines (10 kV to 500 kV), ACSR / AAC / AAAC conductors, straight-line and small-angle towers, pole lines and substation jumper supports.

Customization Service

We provide flexible customization services, including clamp grade XGU-1 to XGU-4 by conductor diameter, with or without armour rods, hanger type (ball-eye, socket-clevis, U-clevis), galvanizing thickness, packaging. Custom marking options include nameplates, logos and project-specific identification to meet traceability and branding requirements.

Q	What is the XGU suspension clamp?
A	XGU-1 ~ XGU-4 Fixed Type Suspension Clamp is an overhead line fitting that supports bare conductors at suspension towers and poles. It is a fixed (rigid-trough) type suspension clamp in which the conductor is held in a curved boat-shaped trough by a keeper plate and U-bolts, and the clamp body swings freely on a top pivot pin so that it can follow the conductor under wind and ice loads. The XGU series is the standard suspension clamp of overhead distribution and transmission lines. The clamp body and keeper are made of hot-dip galvanized malleable iron or cast steel; the trough is curved with flared bell-mouth ends to limit bending stress and protect the conductor strands. The series is graded XGU-1 to XGU-4 by conductor diameter range and rated failure load, so one clamp family covers conductors from small distribution sizes up to large transmission conductors. The hanger ears accept a standard ball-eye, socket-clevis or U-clevis for connection to the insulator string.
Q	Which standards does this suspension clamp comply with?
A	The clamp is designed and tested to GB/T 2314 (general technical specifications for electric power fittings) and IEC 61284 (overhead lines - requirements and tests for fittings), including mechanical failure load, slip load and hot-dip galvanizing requirements. Type test reports can be provided on request.
Q	What is the difference between XGU, XGF and CGU suspension clamps?
A	XGU is the standard fixed type suspension clamp for distribution and transmission lines. XGF is the corona-proof type with a smooth, fully rounded aluminium alloy body and shielded hardware for high voltage lines where corona discharge and radio interference must be limited. CGU is the reinforced type with a longer, deeper trough, additional U-bolts and a stronger hanger for large-section or heavy conductors, long spans and heavy ice or wind loads.
Q	Should armour rods be used with the XGU clamp?
A	Preformed armour rods are recommended for lines with high vibration or where the conductor is small relative to the clamp mouth. They spread the clamping force, protect the strands and improve fatigue life. We can supply the clamp with matched armour rods if the conductor type and size are given.
Q	How do I select the correct clamp size?
A	The clamp is selected by the conductor type and outer diameter (for example ACSR 240/30), the required rated failure load and whether armour rods are used. Please send the conductor specification and line voltage; we will recommend the matching clamp grade and hanger fittings.
Q	Where is this suspension clamp typically used?
A	Suspension points of overhead power distribution and transmission lines (10 kV to 500 kV), ACSR / AAC / AAAC conductors, straight-line and small-angle towers, pole lines and substation jumper supports.
Q	What information do you need for a quotation?
A	Please provide the conductor type and diameter, line voltage, required rated load, hanger connection type (ball-eye, socket-clevis or U-clevis), quantity and delivery destination. We will confirm the clamp grade and quote accordingly.
Q	Do you supply complementary products?
A	Yes. In addition to high and low voltage switchgear, we supply power cables, cable accessories, electric power fittings and transformers for complete project packages.
