ZSI
Frequently asked questions
Common questions about ZSI from 3G Electric.
What are the temperature ratings for ZSI grip-style strut clamps?
ZSI grip-style strut clamps, such as the CG-10, CG-20, CG-30, and CG-40 models, are rated for high-temperature applications. The specific maximum temperature depends on the cushion material, which is thermoplastic vulcanizate (TPE). TPE cushions are formulated to resist degradation at elevated temperatures, but the exact rating should be confirmed with the manufacturer's data sheet. These clamps are commonly used on copper tube in heating and hot water systems where temperatures can exceed 200°F (93°C). For precise limits, consult ZSI's technical documentation or contact 3G Electric for assistance.
What is the purpose of the ZSI AS1 closure strip?
The ZSI AS1 closure strip is a thermoplastic vulcanizate (TPE) strip painted black, designed to fit 1-5/8 in strut channels. It seals the open face of the channel to prevent debris accumulation and reduce contact with channel edges. This helps maintain a clean appearance and can protect cables or pipes within the channel from abrasion. The strip is flexible and snaps into the channel, providing a finished look. It is commonly used in electrical and mechanical installations where open strut channels are present.
What sizes of copper tube can ZSI snap-on hangers accommodate?
ZSI snap-on hangers, such as the QC16, QC18, and QC34 models, are available for various copper tube sizes. The QC16 fits 1 in copper tube (1 1/8 in OD), the QC18 fits 1 1/8 in copper tube (1 1/4 in OD), and the QC34 fits 2 1/8 in copper tube (2 1/4 in OD). These hangers are designed to snap onto the tube and support it from 3/8 in threaded rod. The polyamide construction provides corrosion resistance and electrical isolation. Additional sizes may be available; check with 3G Electric for the full range.
Are ZSI grip-style strut clamps supplied with mounting hardware?
Yes, ZSI grip-style strut clamps include mounting hardware. For example, the CG-10, CG-20, CG-30, and CG-40 models all come with the necessary hardware for installation onto strut channels. This typically includes bolts and nuts to secure the clamp to the channel. The inclusion of hardware simplifies procurement and installation, as separate hardware orders are not required. Always verify the specific contents of the package when ordering, as configurations may vary by part number.
What materials are used in ZSI pipe support components?
ZSI pipe support components use materials selected for durability and performance. Grip-style strut clamps feature a thermoplastic vulcanizate (TPE) cushion, which provides vibration damping, electrical isolation, and resistance to high temperatures. Snap-on hangers are made from polyamide, a strong, non-conductive plastic that resists corrosion and many chemicals. Closure strips are made from thermoplastic vulcanizate and are painted black. These materials are chosen to withstand typical industrial and commercial environments without degrading prematurely.
Can ZSI strut clamps be used with both pipe and copper tube?
Yes, many ZSI grip-style strut clamps are designed to secure both pipe and copper tube. For instance, the CG-40 clamp fits 3/4 in pipe and 1 in to 1 1/5 in copper tube (max OD 1 5/16 in). The CG-30 fits 3/4 in pipe and 1 in, 4/5 in, and 1 1/5 in copper tube. The CG-20 fits 3/8 in pipe and 3/5 in to 4/5 in copper tube. The CG-10 fits 1/4 in pipe and 1/5 in, 2/5 in, and 3/5 in copper tube. This dual compatibility allows for flexibility in piping systems that may transition between pipe and tube.
