As a Design Engineer or User, you should know about Delta Star "Curvback" Clamp Design.

Delta-Star "Curvback" Clamp Design

Delta-Star "Curvback" clamps insure a heavy uniform pressure over the entire clamped surface, and at the same time automatically indicate when the clamps have been sufficiently tightened to secure maximum pressure without bending beyond their elastic limit.With ordinary flat back clamps, pressure is concentrated at the edges and there is nothing to indicate when maximum pressure is reached.  Usually the clamps are tightened until they bow up in the middle and are stretched beyond their elastic limit.  The danger of this condition is readily apparent as further stretching of the clamp may take place either due to fatigue or thermal expansion and contraction.

The latter condition is particularly apt to occur as uneven pressure will result in excessive current at the edges and no current at the middle of the joint, causing heating of the joint during peak load, with periodic expansion and contraction.

"Curvback" Clamp Superiority

The "Curvback" clamp is superior to the flat back type in five essential features.

Due to the curvature of the clamp back, pressure is first applied at the middle of the bus connection.

As the bolts are tightened, the clamps stretch, exerting an even pressure over the entire surface clear to the edges.

When the edges of the "Curvback" clamps firmly touch the copper bus, its serves as an automatic indication that maximum pressure has been secured.

"Curvback" clamps retain their full elasticity as the clamp curvature is such that at no time does the fiber stress reach the elastic limit.

The possibility of the pressure lessening due to fatigue of the metal, thermal expansion and contraction is reduced to a minimum.

Power Connectors Plugs and Receptacles

Since 1919, our power connectors have stood up under extreme conditions where ordinary types have failed. Our design is simple and robust and although these units are higher in original cost, their longer service life, ease of repair and low maintenance costs soon justify the difference.

Simplicity of construction and interchangeability of parts permit low cost maintenance. The various elements of the plug or receptacle are held in position by screwing together the metal housing sections.

With this in mind and the impact of today's economy hindering businesses from making new purchases, Delta Star Connector Company is offering a Re-Work Program for all Plugs and Receptacles.

Here is how this program works:

1.      Send us the Plug (s) or Receptacle (s) that requires unit to be repaired.

Delta Star Connector Company

200 Seegers Ave.

Elk Grove Village, IL 60007

( For Quantities of 10 or more pick-up and delivery is available free of charge)

2.       Upon receiving the unit , Delta Star Connector Company will:

a.       Examine the unit to determine what parts will be needed to make repairs.

b.      Provide a cost to repair quote and a bill of material to the customer for approval. Along with the quote, we will also provide a comparison of the new unit cost versus the cost of repair *.

* The fee for the initial assessment and cost of labor to repair is $ 100.00 per unit + the cost of the replacement parts, which will be highlighted in the Bill of materials provided to you in Item 2.b

We hope that you find this program helpful and in most cases will help reduce the cost of buying a new unit versus re-working the old unit.
