COMPONENT GUIDE

Cutout switch hook / trunnion casting

Hanging or pivot support in an outdoor cutout

Provides a drawing-defined hook or pivot interface in a cutout mechanism.

Manufacturing & delivery form
Hardware casting with pin-hole and mating-face machining.

The hook or trunnion is a drawing-defined mechanical component. Cutout current rating and interruption performance require complete-equipment verification.

Material candidates

UNS C95400 Aluminium bronze

A candidate for specified wear, guidance or structural components.

Candidate for drawing review only. Confirm load, counterface, lubrication and condition; it is distinct from C95800. Zhiren availability is unconfirmed.

UNS C87600 Cast copper-silicon alloy

A candidate for drawing-specified connection or support components.

Candidate for drawing review only. Confirm functional requirements and casting condition; do not substitute wrought copper-silicon or brass grades by family name. Zhiren availability is unconfirmed.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Mechanism geometry: Hook or trunnion configuration, pin fits and movement envelope.
Mechanical duty: Impact, repeated-operation loads, mating parts and acceptance criteria.
Exposure & function: Weathering, corrosion, finish and the boundary between load support and current carrying.
Material specification: Alloy grade, governing standard and revision, manufacturing condition and any restricted substances.
Order & acceptance: Approved drawing revision, quantity, blank or machined delivery, inspection criteria and required records.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.
