GE Lighting makes concessions to Chinese distributors, and three measures properly handle the transition period

On September 29th, GE Lighting officially released a statement of negotiating results with dealers after 10 days of early cancellation of the dealers in China. This is the second official statement by GE Lighting after the internal promotion of commercial activities in Asia and China.

According to the statement, GE Lighting attaches great importance to the recent concerns of some distributors regarding GE Lighting's follow-up arrangements for the termination of business activities in Asia. GE Lighting's global chief operating officer rushed to China in the first time to listen to the dealer's specific demands. On the basis of fairness and impartiality, the Chinese team has defined the following principles for follow-up arrangements to support the smooth transition of dealer business:

1. As previously communicated with the distributor, GE Lighting will fulfill all of the initial warranty commitments for the product until the end of the after-sales warranty period;
2. Will help the dealer to complete the customer order that has won the bid and signed the contract before November 30, 2016. Since the situation of each dealer is different, it will follow up with the dealer one by one, and provide targeted support according to the specific situation;
3. For the dealer's existing inventory, follow up with the dealer one by one, and provide targeted support according to the contract and specific circumstances.
In order to fulfill the above commitments, GE Lighting has set up a dedicated work team to provide strong support to dealers. We believe that through open communication and sincere cooperation with distributors, we will properly handle issues related to the transition period.

From September 1st, the media exposed the internal letter of GE Lighting CEO Bill Lacey to the company's employees. On September 18th, GE China market dealers issued a joint statement to protest, GE's withdrawal from the Chinese market incident was full of enthusiasm.

Under pressure, GE Lighting released its first official statement on the official website five days after the distributor's joint statement.

According to the statement, GE Lighting announced the termination of its business activities in Asia at the end of August 2016 based on business considerations. This is a very difficult decision.

Recently, we have noticed that some GE lighting distributors have doubts about the follow-up arrangements for this decision. We deeply understand and concern about this. In response to the specific demands put forward by some dealers, we attach great importance to and are actively communicating to ensure that consensus on the issues of concern to distributors is reached on the basis of fairness and fairness.

GE has a long-term commitment to the Chinese market and has always valued the partnership with all its partners. We will continue to invest in and expand the Chinese market, and we will continue to grow together with our Chinese partners.

But it is clear that the changes from GE Lighting to GE's terminology have shown that at least the lighting business in China is no longer the core business of GE.

Surge Protection Device SPD

Product Description

SPD Surge Protective Device,Lightning Surge Protector
Surge Protection Device (SPD)

It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component.

Surge protective Device Model Selection

With the impact of international information flow, the rapid development of microelectronic science and technology, communication, computer and automatic control technology, make the building start to go for high quality, high functional area, formed a new building style-intelligent building. As inside the intelligent building there are lot of information system, <<Building lightning protection design norm>> GB50057-94(2002 vision)(hereafter brief as <<lightning protection norm>>) put forward the relative requirement to install the surge protective device, to ensure the information system safely and stable running.
SPD essentially is a equipotential connection material, its model selection is according to the different lightning protection area, different lightning electromagnetic pulse critical and different equipotential connection position, decide which kind of SPD used in the area, to achieve the equipotential connection with the common earth electrode. Our statement will based on SPD's maximum discharge current Imax, continuous operating voltage Uc, protection voltage Up, alarm mode etc.
As per << Lightning Protection Norm>> item 6.4.4 stipulation "SPD must can withstand the expected lightning current flow and should confirm to the additional two requirements: the maximum clamp voltage during surge across, capable to extinguish the power frequency follow-on current after lightning current across." That is the value of SPD's max. clamp voltage add its induction voltage of two ends should be same with the system's basic insulation level and the equipment allowed max. surge voltage.

SPD for Power Supply System Series Selection Guide

The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity.
The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.
SPD for power supply system specification selection principle
Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage.
TT System: Uc≥1.55Uo (Uo is low voltage system to null line voltage)
TN System: Uc≥1.15Uo
IT System: Uc≥1.15Uo(Uo is low voltage system to line voltage)
Voltage Protection Level: less than the insulation withstand impulse voltage of protected equipment
Rated discharge current: determined as per to the lightning situation of the position installed and lightning protection zone.
